Post by: Ajamu on Jul 01, 2013, 07:55 PM
No i ain't hardly talkin bout spendin alotta $$$ on a computer (it's usually not necessary for most of the stuff people usually do), but if battery life is real important to you ....

Don't buy a new PC or Mac before you read this | Reviews - Laptops - CNET Reviews (http://reviews.cnet.com/8301-3121_7-57591398-220/dont-buy-a-new-pc-or-mac-before-you-read-this/)

Don't buy a new PC or Mac before you read this


 Is  the laptop, desktop, or tablet you plan to buy stuck with a last-gen  CPU? That may be a reason to wait -- or a way to get a great deal.  Here's how to tell.

  While summer break has just started for students across the country,  that means that the all-important back-to-school shopping season is not  far behind. And with it comes a flood of new or updated systems --  everything from traditional laptops and desktops to tablets and hybrids.  
 
But before swiping your credit card on a new ultrabook, all-in-one, or  convertible, you're going to want to dive a little deeper into the spec  sheets. That's because the latest Intel CPU upgrade -- code named Haswell (http://reviews.cnet.com/8301-3121_7-57587411-220/intels-new-fourth-gen-haswell-processors-what-you-need-to-know-faq/),  but officially known as "fourth-generation Core i series" -- is  offering significant battery life improvements in the first wave of  laptops we've tested so far. So, unlike the more ho-hum Intel updates  we've seen in years past, there's a real-world payoff in seeking out a  Haswell-equipped laptop.
 
On the other hand, if battery life isn't a big concern -- if you're  going for a desktop PC, or if you have a "desktop replacement" laptop  that you don't tend to disconnect from the power cord -- you could score  a nice discount on the many pre-Haswell PCs that will inevitably make  their way to the discount bin.

 How do you tell which is which? That's the tricky part.
 
The current laptop landscape


 As we move into the Haswell era, the market is in flux. Many "new" laptops and hybrids, such as the Lenovo IdeaPad Yoga 11S (http://www.cnet.com/laptops/lenovo-ideapad-yoga-11s/4505-3121_7-35560383.html), Acer Aspire R7 (http://www.cnet.com/laptops/acer-aspire-r7/4505-3121_7-35757122.html), or the Toshiba Kirabook (http://www.cnet.com/laptops/toshiba-kirabook-core-i7/4505-3121_7-35667194.html),  all still ship with processors from Intel's third-generation Core i  series, the same parts that have been found in most PCs since spring  2012. Only a handful of more-forward-looking systems already have  Intel's just-released fourth-generation Intel Core i-series Haswell  processors.

  (https://www.abibitumikasa.com/proxy.php?request=http%3A%2F%2Fasset0.cbsistatic.com%2Fcnwk.1d%2Fi%2Ftim2%2F2013%2F06%2F13%2FApple_MacBook_Air_13-inch_35781451_06_610x436.jpg&hash=d35ee82b658968a99834bca43d6a1733d11b2246)

Need a 14-hour laptop? Get the new 13-inch MacBook Air.
 
 Normally that wouldn't be a big deal, because any current laptop will  have more than enough processing power for everyday tasks, such as Web  surfing, HD video playback, social media networking, and working on  basic office documents. For that reason, in years past, having the  latest and greatest processors wasn't especially high on my priorities  list. Frankly, the average consumer wouldn't feel much of a difference  in surfing the Web on a laptop with a budget-minded Intel Core i3 versus  one with a high-end Core i7.
   
  But with only a handful of Haswell PCs (and Macs) tested so far, the battery life results from them so far has been very impressive (http://reviews.cnet.com/8301-3121_7-57586951-220/intels-next-gen-quad-core-processors-tested/).  The Haswell-equipped PCs also offer Intel's better integrated graphics,  either the HD 5000, HD 4600, or HD 4400, rather than the now-outdated  Intel HD 4000 graphics found in third-gen Core i-series systems.

  Case in point: the 2012 version of Apple's 13-inch  MacBook Air (http://reviews.cnet.com/laptops/apple-macbook-air-13/4505-3121_7-35330106.html) ran for 7 hours and 27 minutes in our video playback battery drain test. The 2013 version of the 13-inch Air (http://www.cnet.com/apple-macbook-air-13-inch/),  with a Haswell CPU, blows that out of the water, with an astonishing 14  hours and 25 minutes on the same test. Sony's Haswell-powered Vaio Pro 13  (http://www.cnet.com/laptops/sony-vaio-pro-13/4505-3121_7-35781040.html)ran for nearly 9 hours, and even the gaming-oriented Razer Blade (http://www.cnet.com/laptops/razer-blade-14-inch/4505-3121_7-35780325.html),  currently still undergoing benchmark testing in the CNET Labs, seems to  have an extended running time compared with older gaming laptops,  thanks to its current-gen CPU.

 How to choose

  The natural question this raises is: Should you hold off on buying a  particular PC if it still has a third-generation Intel Core i-series  processor and wait for the Haswell version? That might mean waiting for a  long time indeed in some cases, potentially missing the back-to-school  window. Some popular laptops, including the Lenovo Yoga line and Toshiba  U series of ultrabooks, have not announced any firm plans to offer  Haswell versions (though it's safe to assume they'll be popping up  eventually).

 (https://www.abibitumikasa.com/proxy.php?request=http%3A%2F%2Fasset3.cbsistatic.com%2Fcnwk.1d%2Fi%2Ftim2%2F2013%2F06%2F03%2FSony_VAIO_13_Duo_35781324_04_610x436.jpg&hash=aaf44abfe233585f3a5bd38ac1c438deff932a34)

 Sony's Haswell-powered Vaio Duo 13.
 
  I suggest approaching with caution, although I'm not ruling out  buying a non-Haswell system altogether. Below are some guidelines that  represent my current thinking on the subject; feel free to add your own  suggestions and ideas in the comments section below.

Desktops and larger laptops: Buy now

Considering the modest gains in actual application performance  (including the HD 5000 graphics), if you're holding off for performance  reasons, don't. For a traditional desktop or all-in-one with no battery,  the last-gen processor isn't a big deal. The same goes, to a lesser  extent, for larger 15-inch and up laptops, which by their nature spend  most of their time tethered to a desk and power outlet.

 (https://www.abibitumikasa.com/proxy.php?request=http%3A%2F%2Fasset2.cbsistatic.com%2Fcnwk.1d%2Fi%2Ftim2%2F2013%2F05%2F03%2FToshiba_Kirabook_35667194_02_610x436.jpg&hash=90206c1d3f55b38388600001efac6055f734c66d)

 The high-end Toshiba Kirabook costs more the $1,500, but has last-gen processors.
 
  Ultrabook-style systems: Seek out a Haswell version

Some of the best ultrathin laptops, namely the Apple MacBook Air and  Sony's new Vaio Pro (both of which are available in 11- and 13-inch  models), are among the first laptops to get the new Intel CPUs. Battery  life on these is amazing, and I'd be hard-pressed to buy a premium  ultrabook (or fauxtrabook) with shorter non-Haswell battery life. It  would certainly be painful to spend more than $1,600 on a Toshiba  Kirabook or Lenovo Helix and not get the latest processors (and the  resulting boost in battery life).

Budget shoppers: Wait if you can, or seek out bargains if you can't

Some of our favorite reasonably priced laptops, such as the Toshiba U-series ultrabooks (http://www.cnet.com/laptops/toshiba-satellite-u845t/4505-3121_7-35566940.html) and Sony's relatively new Vaio Fit 14 (http://www.cnet.com/laptops/sony-vaio-fit-14/4505-3121_7-35757138.html),  are not available with fourth-gen Intel Core i-series CPUs yet, nor is  there an estimated date for them. The new Core i3 CPUs for budget and  midprice systems are the last item on Intel's priority list (the  highest-end quad-core Core i7 chips came out first, followed by Core i5  versions), and more-modest battery life expectations are built into  buying a sub-$800 laptop. That said, we're already seeing some good  deals on pre-Haswell PCs, as retailers and manufacturers begin blowing  out inventory to make room for those new Haswell models. So this summer  see a lot of $800 to $900 PCs going for as little as $600. Keep an eye  on those Sunday newspaper circulars and Internet deals.

Tablet/hybrids: Wait for Haswell

Tablets are designed for all-day on-the-go use, but to date, Windows  models -- from the new Lenovo Yoga 11S to the Acer Aspire P3 to the  Microsoft Surface Pro (http://reviews.cnet.com/microsoft-surface-pro/) -- just haven't yet hit that iPad sweet spot. Well, it's time to stop compromising. Every  Windows 8 (http://reviews.cnet.com/windows-8-review/)  device that's either a slate-style tablet or laptop/tablet hybrid could  benefit from the extended battery life offered by Haswell. (That also  goes for Intel's next-gen Atom CPU, dubbed Bay Trail (http://news.cnet.com/8301-1001_3-57583034-92/intels-new-mobile-chip-to-boast-up-to-8-processor-cores/)  -- also due soon.) The 14-hour battery life on the new MacBook Air  proves it: it's possible to get much better battery life on tablets than  we're getting now, and we should demand it. In other words, if you like  the look and feel of a current Windows tablet, hold out for the Haswell  version.

 Bonus advice: Don't worry about Windows 8.1 or Mac OS X 10.9 Mavericks

Savvy tech shoppers know that Microsoft and Apple are both updating their operating systems before the end of the year, to Windows 8.1 (http://reviews.cnet.com/operating-systems/microsoft-windows-8-1/4505-3671_7-35798810.html) and Mac OS X 10.9 Mavericks (http://reviews.cnet.com/apple-os-x-10.9-mavericks/).  The good news is that the Microsoft upgrade will be free (for existing  Windows 8 users), and the Mac upgrade is likely to be very cheap (Apple  hasn't announced pricing, but the last few Mac versions have been only  $20). Any computer running the current OSes should be easily upgradeable  to the forthcoming versions; there's no reason to wait for them to be  released before buying.

Laptop buying guide - CNET Reviews (http://reviews.cnet.com/laptop-buying-guide/)

The most important things to know when shopping for a new laptop, hybrid, or Windows tablet.

   (http://www.cnet.com/profile/Dan_Ackerman/)    by Dan Ackerman (http://www.cnet.com/profile/Dan_Ackerman/)

While our laptop and mobile PC buying guide will give you  the tools to go out and research, shop for, and buy the perfect laptop,  hybrid, or Windows  tablet (http://reviews.cnet.com/tablets/), there's no harm in starting off with a few favorite picks for 2013.

 It's hard to go wrong with the latest version of Apple's MacBook Air (http://reviews.cnet.com/apple-macbook-air-13-inch/). Both the 13-inch and 11-inch (http://reviews.cnet.com/apple-macbook-air-11-inch/) models have updated Intel Core i5 processors and excellent battery life. For a Windows version of something similar, check out Sony's 13-inch  (http://www.cnet.com/laptops/sony-vaio-pro-13/4505-3121_7-35781040.html)and 11-inch Vaio Pro (http://www.cnet.com/laptops/sony-vaio-pro-11/4505-3121_7-35781039.html) laptops, which are similarly built around Intel's new fourth-generation Core i-series CPUs. The Lenovo IdeaPad Yoga 13 (http://www.cnet.com/laptops/lenovo-ideapad-yoga-13/4505-3121_7-35477652.html) remains the best example of the  Windows 8 (http://reviews.cnet.com/windows-8-review/) hybrid laptop/tablet device, but it's currently stuck with previous-generation CPUs.

Since the 2012 version of our buying guide, a couple of big-picture  things have changed. Windows 8 is now the default operating system, and  its tile-based interface means that touch screens are now standard in  nearly every new laptop. And, after years of few if any Windows tablets,  the Win 8 era has given us dozens of them, and many are not just basic  slates, but ambitious hybrids with flipping, rotating, or even  detachable screens.

 Most buying guides and shopping advice tend to get bogged down in the  specs, mechanically listing subcategories within subcategories. Instead,  I'll break out the most important things to know when looking for a new  laptop, with deeper explanations available in any of our in-depth  system reviews. To start with, here are my three cardinal rules for buying a laptop.
 
Three rules for buying a laptop

 1. Don't buy too much laptop

 Go back several years, and $1,000 was considered a good price for a  budget laptop. Today, that's considered premium, and only one company,  Apple, gets away with regularly charging much more than that (but that  doesn't stop others from trying).  So when a reader e-mails us to say something along the lines of: "I'm  looking for a laptop for school, and I've only got $1,500 to spend," we  generally tell them to ease up on the gas pedal and look at a mainstream  slim laptop for $700-$800 or so as a starting point.

 And it's not just underpowered plastic boxes in that price range,  either. Intel Core i5 CPUs and touch screens in slim, reasonably  attractive bodies, with 128GB SSD hard drives are available in that  price range -- which is more than adequate for most users, unless you're  planning on editing a lot of HD video or playing very high-end PC  games.
 Long story short, consumers have been buying too much laptop for years.  The brief era of $300 Netbooks took them too far in the other direction,  and now we've comfortably settled at a happy medium. Touch screens and  hybrids have moved average prices up a bit, but $999 or less can still  snag you an excellent premium laptop or hybrid.

2. Think about traveling light

 The first question I have when someone asks, "What kind of laptop should  I buy?" is this: How many days per week to you plan on carrying your  laptop around with you?  The answer to that should determine what screen size your laptop should  have, which largely defines the system size and weight. Frequent  commutes suggest a lightweight 13-inch ultrabook (similar to the MacBook Air (http://www.cnet.com/laptops/apple-macbook-air-13/4505-3121_7-35330106.html)).  Making a surprising comeback are ultraportable laptops with 11.6-inch  screens, including several recent 11-inch hybrids and Windows tablets,  where you may only have to take the screen with you and leave the  keyboard base at home or the office.

 More common midsize laptops, such as the 15-inch model probably sitting  on your desk right now, are really not much fun to lug around more than  once a week or so.

 Lastly, if you're convinced you're never going to need to take your  laptop along with you, or at best very, very rarely, then a big 17-inch  or larger desktop replacement is a viable option. Keep in mind that most  of these big laptops can't run for very long away from a power outlet,  and very few we've seen so far in the Windows 8 era have touch screens.

3. Design is king

 If there's one thing we've learned from benchmarking and testing  hundreds of laptops, it's that under the hood, a lot of these systems  are awfully similar. I'd go so far as to say that, with most laptops  constructed from the same pool of stock CPUs, hard drives, RAM, and  video cards, it's dangerously close to being a  commodity product (http://en.wikipedia.org/wiki/Commodity).  That's where design comes in. If most laptops within a given class, and  with similar components, are going to run similarly, it's the look and  feel that's really going to push you toward one model over another.

 Think of a laptop as a very visual extension of your personality. You  may carry it around with you all day, or even all over the country. You  send e-mails from it, store personal photos and documents, and use it to  connect with people on social networks.

  (https://www.abibitumikasa.com/proxy.php?request=http%3A%2F%2Fasset1.cbsistatic.com%2Fcnwk.1d%2Fi%2Ftim2%2F2013%2F06%2F13%2FApple_MacBook_Air_11-inch_35781454_11_610x436.jpg&hash=2d55917182abaee2d1cc9da982c3d0f5aa70107f)  
(Credit: Sarah Tew/CNET)  

  Like any personal accessory, such as a jacket or a pair of glasses,  you should choose a laptop with a style and design that works for you,  as well as one with a keyboard and touch pad you find comfortable and  easy to use. That's what Apple nails really well -- the parts inside of a  MacBook are not that different from other laptops (although the  operating system is another story), but the human interface tools are  fantastic, and the design has become a standard for what a lot of people  think a laptop should look like.

 The current fad for thin ultrabooks backs this up, as well as the hype  that high-design laptops such as the Samsung Ativ 9 or Asus Transformer  Book inevitably generate.

 A laptop is a big investment that you'll probably have to live with  every day. If it comes down to choosing between a design you love and a  minor difference in specs, I'd point out that nearly all mainstream  laptops are powerful enough for everyday computing tasks, so go with a  great design.

The categories

 There are many ways to categorize laptops, and we've seen systems  chopped into multimedia, gaming, thin-and-light, ultrabook, ultraslim,  and ultraportable. You'll see the term "ultrabook" used a lot.  It's not technically a laptop category, but instead a trademarked Intel  marketing term, bestowed on laptops that meet Intel's requirements. Most  are MacBook-Air-like thin 13-inch laptops, but you'll also find 14- and  15-inch ultrabooks. We sometimes call systems that are similarly thin  but don't meet Intel's sticker requirements "fauxtrabooks," or just  ultrabook-like.  As a way to cut through the clutter, we use screen size as the primary  category definition for laptops -- which ties nicely in with our advice  above on choosing a laptop based on how often it will travel with you.  Here are the most common laptop categories you'll find on CNET.

 (https://www.abibitumikasa.com/proxy.php?request=http%3A%2F%2Fasset1.cbsistatic.com%2Fcnwk.1d%2Fi%2Ftim2%2F2013%2F06%2F13%2FApple_MacBook_Air_13-inch_35781451_07_610x436.jpg&hash=a9e9d5cfa1fe45d1af6c181f793954dbe967016c)

Ultraportable  (http://reviews.cnet.com/best-ultrabooks/)(11-to-12-inch displays)
Ultraportable systems with 11- and 12-inch screens are making a  comeback, thanks to new laptop entries from Sony and Apple, and hybrids  from Lenovo, HP, and others. These typically have low-voltage Intel Atom  CPUs, or sometimes AMD E-series chips. The 11-inch Windows 8 tablets  can start for as little as $499, and go up from there, usually asking  another $100 or so for a keyboard dock.

 13-inch laptop  (http://reviews.cnet.com/best-thin-light-laptops/)
The only screen size distinctive enough to earn its own category, these  systems occupy a unique space in the industry. A 13-inch laptop is the  smallest size we'd be able to work on comfortably all day, and at the  same time, the largest size we'd consider carrying around more than once  or twice a week. Apple's  MacBook Pro (http://www.cnet.com/macbook-pro-13-inch-retina-display/) and Air and the Sony Vaio Pro 13 are popular examples.

 As previously mentioned, "ultrabook" is a trademarked Intel term, but  it's largely taken to mean a lightweight 13-inch laptop that's under  18mm thick, with SSD storage. We're almost at the point where most, if  not all, 13-inch laptops are nearly ultrabook-thin, and the use of the  marketing term may fade. In other words, when everything is essentially  an ultrabook; it won't need a special name.

Some hybrids and  convertibles also fall into the 13-inch category, although a 13-inch  tablet screen is a bit on the unwieldy side.

 Midsize  (http://reviews.cnet.com/best-mainstream-laptops/)(14-, 15-, and 16-inch displays)
The traditional 15-inch laptop, along with its less-common 14- and  16-inch offshoots, make up this category. Although technically mobile  products, mainstream or midsize laptops tend to stay anchored to one  location, or only move around within a single home or office.

 Most midsize laptops have dual-core or quad-core CPUs, most commonly  from Intel's Core i-series line, along with 4GB or 8GB of RAM, and large  hard drives with at least 320GB of storage space. High-end extras such  as discrete GPUs and Blu-ray drives are uncommon but available. Intel  also allows for some 14- and 15-inch laptops to use the ultrabook name,  if they meet certain size and spec requirements, but that's rare.

 The midsize category covers the widest ground in terms of price and  features, starting at around $500 and going well past $1,000. Most  typical are $800 to $1,000 configurations.

 Desktop replacement  (http://reviews.cnet.com/best-desktop-replacements/)(17-inch or larger display)
These massive 17-inch and larger laptops are meant to literally replace  your old desktop, monitor, and keyboard combination with a single device  that can also be easily transported in a pinch.

 Quad-core CPUs are common, as are discrete graphics cards from Nvidia or  AMD. We'd ask for a full 1080p screen, which is 1,920x1,080 resolution,  and perfect for playing back Blu-ray or high-def digital content.

 While 17-inch screens are more common, there are a handful of 18-inch  models, and these large desktop replacement laptops make good hybrid  entertainment centers for the den or dorm room, putting your computing,  video, and music devices in a single box. We've also seen 18-to-20-inch  all-in-one desktops with detachable screens that become, in essence,  giant tablets of varying portability.

 (https://www.abibitumikasa.com/proxy.php?request=http%3A%2F%2Fasset2.cbsistatic.com%2Fcnwk.1d%2Fi%2Ftim2%2F2013%2F06%2F24%2FLenovo_Yoga_11S_35560383_03_610x436.jpg&hash=97e09367d652fd68606a8575fe7b91eb1d4fe295)
 
Hybrids, tablets, and convertibles  (http://reviews.cnet.com/best-touchscreen-hybrid-laptops/)

The majority of mobile PCs with screens that detach, flip over, or fold  down to a slatelike shape have screens between 11.3 and 13.3 inches, and  behave largely like traditional clamshell laptops in the corresponding  groups above. Some, such as Lenovo's Yoga series, really do look and  feel like regular laptops most of the time, while others, including  Microsoft's Surface Pro, are meant to spend more time in tablet mode.

 Intel Atom and Core i5 CPUs are common, which is why some hybrids cost  $499, and others more than $1,000. Few models are really ready to be  mainstream consumer products yet, largely because Windows 8 still  doesn't feel fully baked as a tablet OS. Plus, many of the detachable  keyboards and touch pads for these systems are terrible. That said, if  you're looking for a smaller laptop, we'd definitely recommend checking  out a few hybrids of the same size, in addition to clamshell laptops.

CPUs/processors

 Like it or not, you still have  to pay at least some attention to specs and components. Here are the  current Intel and AMD processors, and where you're most likely to find  them.  AMD

This company (also the parent of the GPU maker formerly known as ATI) has recently launched new generation of accelerated processing units (http://reviews.cnet.com/8301-3121_7-57585760-220/amd-launches-new-processors/),  previously known by the Temash, Kabini, and Richland code names. Rather  than CPU, or central processing unit, AMD these days uses the term APU,  or accelerated processing unit, meaning that a CPU and discrete-level  GPU are combined.

 You'll most likely find the new AMD A4, A6, A8, and A10 chips in  upcoming systems from Acer, HP, and others in roughly the same time  frame as Intel's next-gen Haswell chips, but offering welcome options  for the budget- and midpriced-PC shopper. Note that far fewer laptops  are available with AMD processors than Intel ones. AMD has a list of current processors here. (http://www.amd.com/us/products/notebook/apu/mainstream/Pages/mainstream.aspx#1)

 Intel
If you're looking at a laptop, tablet, hybrid, or even a desktop PC,  chances are it has an Intel CPU in it. The current line confusingly has  the same product names as the previous three generations. But the new  chips, launched starting in June 2013, are also known by the code name Haswell  (http://reviews.cnet.com/8301-3121_7-57586951-220/intels-next-gen-quad-core-processors-tested/)(the previous generation was Ivy Bridge).

These 2013 fourth-generation CPUs are easy to spot, as most have a  part number that begins with the number 4. For example, Sony's new Vaio  Pro 13 has a 1.6GHz Intel Core i5-4200U CPU. A more detailed list of  processors is available from Intel here (http://ark.intel.com/#mobileprocessors).

The  performance difference between last-gen and current-gen CPUs is modest.  However, Haswell has offered significant battery life improvements in  the first wave of laptops we've tested so far, passing 12 hours in the  13-inch MacBook Air. There's a real-world battery life payoff in seeking  out a Haswell-equipped laptop, and we'd wait for whatever model you're  looking at to be updated if it's going to be used frequently on the go.

Hard drives and storage

 Your new laptop is going to have either a traditional spinning platter  hard drive (HDD), or a solid-state hard drive (SSD), which is flash  memory, similar to what you'd find in an iPhone or SD card. We've also  seen a few examples of hybrid drives, where a small SSD (perhaps 20GB or  32GB) is paired with a larger HDD. In theory, this lets the system boot  faster and helps apps open quickly, but stores bulky music and video  files on the standard hard drive.

Frequently Asked Questions

What kind of ports and extras do I need?

A couple of USB ports are a minimum. Most laptops now include at least  two USB 3.0 ports, which are faster than the older USB 2.0 version, but  only when used with compatible USB 3.0 devices, such as external hard  drives. An SD card slot should be non-negotiable, as well as an HDMI  video output. Every laptop includes Wi-Fi now, and will be compatible  with virtually any Wi-Fi signal or router.

What kinds of ports and extras can I skip?

The old-style VGA video output still shows up on most laptops, but  unless you need to connect to something like an old CRT monitor, it's  not required. DisplayPort for video or Thunderbolt (another high-speed  data connection) are only needed if you have compatible hardware. An  Ethernet jack often gets skipped on the thinnest laptops in favor of  Wi-Fi. It's better to have it for emergencies, but it's not the end of  the world if you don't have it. Bluetooth is useful, but only if you  have a Bluetooth mouse, speaker, or headset you plan to use; otherwise  skip it or turn it off to save battery life.

 Do I need an optical drive?

The answer is trending toward "no," and a good number of thin,  lightweight laptops now skip the optical drive. We haven't missed it,  but some people are definitely still tied to CDs or DVDs as a storage or  media playback format. That said, there are still many people tied to  optical media, so for them, it's a must-have.

 Do I need a graphics card?

Unless you plan on playing serious PC games on your laptop (Skyrim,  Metro: Last Light, and so on), you can get away with using the graphics  capabilities built into laptops by default. Intel's current version is  called HD 5000, and while it's not for serious gamers, you should be  able to get away with playing casual or older games, or even newer games  if you keep the visual settings set to Low.

  Should I get a tablet or a laptop?

Windows tablets have disappointed for years, but the current Windows 8  generation is definitely showing signs of life. Especially because Win 8  is built for touch-screen use (although it's far from perfect), and  most Windows 8 tablets and hybrids have a laptoplike mode or accessories  that make them more universally useful. If you're doing a lot of typing  or touch-pad navigation, I'd still stick to a traditional laptop, or at  best a very laptoplike hybrid, such as Lenovo's Yoga line.

 What's better, Windows or Mac OS X?

That's a loaded question if there ever was one. Windows users appreciate  the flexibility of that operating system, allowing for extreme tweaking  and personalization. It's available on a nearly limitless variety of  hardware, and with Windows 8, Microsoft has created a much more touch-  and tablet-friendly OS, with a slick, modern look that's a big break  from the past.

 Apple's operating system, on the other hand, is only available on a  handful of desktops and laptops. That said, the joint hardware/software  platform makes for a much more stable/predictable overall experience,  and many prefer the user-friendly OS X layout and controls. Finally,  Windows has a much larger available software library, especially when it  comes to free software and games.

 Should I buy now, or wait for the next update/upgrade/OS/CPU/etc.?

That's the million-dollar question, and it applies to nearly every  technology category. Every new piece of hardware is a step closer to  obsolescence with each passing day, and there's always a new version  coming at some point in the not-too-distant future. Once you accept  that, it's a lot easier to just relax and buy a product you'll enjoy  using, without succumbing to upgrade envy.

 There is, for the moment at least, a notable exception. If you're  shopping for a specific laptop, tablet, or hybrid that you plan to use  on the go, then we strongly suggest waiting until it has been updated  with Intel's newest fourth-generation Core i-series CPUs, because of the  amazing battery life gains we've been seeing in these Haswell-powered  systems. Apple's MacBook air laptops have been updated, as have some  products from Sony, Dell, and others.
