PlayStation 4 Review and Specification

Posted On //
PlayStation-4
The good: The PlayStation 4 serves up dazzling graphics, runs on a simplified and logical interface, and boasts a fantastic controller. It's also $100 cheaper than rival Xbox One and has the upper hand on indie and day one digital-only offerings.

The bad: Triple-A titles are lacking at launch, and the PS4 won't come close to matching its predecessor's gaming or software library for months -- or possibly years. PS3 games aren't compatible, though Sony is hinting that its Gaikai game-streaming service will open the door to retro gaming in 2014. The PS4 also has no DLNA compatibility or media playback support which made its predecessor such a great all-around content player.

The bottom line: The PlayStation 4's beautiful graphics, blazing interface, and near-perfect controller make it a worthy successor to the PS3, but it would be wise to wait for more titles and features before you buy.

The hardware 
Despite its smallish size -- at least compared with an Xbox One -- the PS4 packs a lot of power under the hood. The box is 2 inches high by 11 inches wide by 12 inches deep, weighs about 9 pounds, and packs in 8GB of DDR5 RAM. The CPU is a low-power x86-64 "Jaguar" eight-core chip, and the graphics are powered by a 1.84 TFLOP AMD Radeon "next engine." The fine print may not impress the layperson, but suffice it to say, the PS4's innards are in line with a mid- to high-end gaming PC.

Like previous PlayStations before it, the PS4's 500GB hard-disk drive is user replaceable (a standard SATA laptop hard drive or SSD will work), something I'm thrilled Sony has decided to keep intact. That 500GB may seem like more than enough storage, but with game sizes beginning to flirt with 50GB apiece, that might not cut it a few years down the road.

The PS4 boasts a striking angular design with a modestly low profile. The front end angles toward the user, sleekly hiding two USB 3.0 slots to the right and a slot-loading 6x Blu-ray drive to the left. Between these two ports are touch-sensitive power and eject buttons that give off familiar PS3 beeps when activated.

Should I buy a Kindle Fire tablet or a Kindle ebook reader

Should I buy a Kindle Fire tablet or a Kindle ebook reader

Tablets and ebook readers both let you read digital books, but they are built around very different screen technologies. For this reason, the Kindle Fire tablets and the Kindle ebook readers are very different devices.

Amazon Kindle Paperwhite
Kindle ebook readers

The Kindle ebook readers use e-ink screens, which imitate the look of a paper screen closely.

This means that they don't reflect sunlight the way a shiny tablet LCD screen can, and they typically use no power when a page is displayed, and only require power when you turn from one page to the next or download books.

Traditionally, Kindle ebook readers have had no built-in lights, but the latest Paperwhite range lets you illuminate the page for reading in the dark.

These e-ink screens are easy on the eye when you're reading for long periods, and they're energy efficient. However, they're black-and-white only, and you can't play back videos on them.

What we think: The e-ink screens are better suited to bright light and reading for long periods, and the battery life beats a tablet's. If you're purely looking to read books, this is the style to go for.

Amazon Kindle Fire HD

The Kindle Fire tablets use full-colour, high resolution LCD touchscreens. This means you can watch videos, play games, read full-colour magazines and browse websites just as you can on other iPad-style tablets.

The downside is screens like this aren't as comfortable to use for prolonged periods of reading, as it can be a strain on the eye to stare at a glowing LCD screen for so long.

Battery life can be another issue. While displaying an ebook isn't particularly taxing on a tablet's screen, it can't compare to the zero power use of an e-ink page.

What we think: The colour screens let you do much more than just read books, though you may not find this style of screen as easy to read in bright light or for long periods.

Do I need a 3G Kindle?

If you're buying a Kindle ebook reader, like the Paperwhite range, you can choose from wi-fi only models, or models with wi-fi and 3G internet.

3G means you you can download books wherever you are using mobile data, and you won't have to pay each time. Instead, you pay more for the initial cost of the ebook reader itself.

The £60 extra fee for 3G connectivity isn't to be sniffed at. This is a high premium to pay given that the only things you can do on Amazon's 3G network are downloading books or accessing Wikipedia.

It's only really worth it if you know you'll buy lots of books when on the move, or if the recipient - if giving as a gift - doesn't have wi-fi in their home.

What we think: If you have wi-fi at home, there's little reason to pay extra for 3G as well.



Do I need a keyboard or touchscreen?

All of the models in Amazon's latest line-up have a touchscreen, with the exception of the basic Kindle.

The Kindle Fire tablets are built around their touchscreen approaches, but the Paperwhite ebook readers also find good uses for touchscreen control.

A touchscreen makes it easy to type in the name of the book or author on the on-screen keyboard. Changing pages with a touchscreen can feel more natural than pressing the button on an ebook reader, and it's easy to select words or passages to look up definitions.

The older Kindle Keyboard 3G model is no longer widely available, but it's possible to track down online. The keyboard is useful if you add a lot of annotations as you read, or when you're typing the names of books or authors in the Kindle store.

Verdict: Most new models now have touchscreens, but if you're determined to have a keyboard, you'll have to buy an older Kindle.



Can I listen to music or audio books on a Kindle?

The new Kindle Paperwhite and best-selling basic Kindle don't support MP3 playback. So if you want to listen to music or audio books then you'll need to buy an older Kindle Touch or  Kindle Keyboard.

These models can also read English language texts out loud to the user, though in a rather robotic voice.

What we think: You can only listen to MP3 files on older Kindles and even then this is arguably easier to do with a smartphone or MP3 player, which will be pocket-sized.


Can I just get an app for my phone or tablet instead?

With smartphones and tablets becoming more popular and including larger higher resolution screens you might be tempted to opt for an ebook reader app rather than forking out for a whole new device.

With free Kindle apps available for most devices it is a much cheaper option than buying a new device, though tablets and smartphones aren't as suited to long periods of reading as an e-ink screen.

See how the Kindle Android app and Kindle iOS app compare to dedicated ebook readers our lab tests.

What we think: It's free to download an app to your tablet or smartphone, but using these screens for long periods may not be as appealing as an e-ink display.
