Sony Xperia Tablet Z shortreview

Sony Xperia Tablet Z: Size and build

The Android -toting Sony Xperia Tablet Z weighs in a just 495g, compared to the 660g iPad 4 and the 597g Samsung Galaxy Note 10.1. We were genuinely surprised when we first got our hands on the tablet - it really is amazingly light and easy to hold in one hand.

Both the design and build quality are similar to that of the Sony Xperia Z smartphone, with the tablet sporting a similarly slimline design, measuring just 6.9mm in depth.

The back of the tablet is crafted from a glass reinforced polymer, which means that it has a nice grippy texture as well as being extremely light.

Sony Xperia Tablet Z: Features

Like the Xperia Z phone, the new tablet is waterproof up to 1m for up to 30 minutes, handy for using in the kitchen without having to worry about any spillages. Although you can't actually operate the screen while it's completely submerged, you can use it when the screen is wet or you have wet hands.

The tablet features a similar UI to the Sony Xperia Z phone - a design experience that Sony is trying to use across all of its connected product, including TVs.

Powered by a Qualcomm Snapdragon S4 Pro quad-core processor, clocking in at 1.5GHz, the Xperia Tablet Z is the first tab to use this particular chip, which also appears on the Xperia Z smartphone.

There'll be 16, 32 and 64GB models available with the 32GB version offering LTE/4G and there's also a micro SD slot on board for boosting the storage.

Connections include Wi-Fi, Bluetooth, NFC and DLNA so there are plenty of options on board for hooking up to other kit around the house. The tablet can also be used as a universal remote for TVs, thanks to the onboard IR tech and an app that works with all the AV brands you could possibly think of and more besides.
The tablet is currently running Android 4.1, but an upgrade to Jelly Bean is due in the not too distant future.

Sony Xperia Tablet Z: Screen

The tablet's 10.1-inch scren sports a 1920x1200-pixel resolutionThe According to Sony, the new tablet has the widest colour spectrum of any tablet, while the brand's Mobile Bravia Engine 2 processing has been used to intelligently adjust the contrast and sharpness.

There are four speakers on the tablet, two on the sides and two on the bottom edge. The idea is that at least two of the speakers remain uncovered at any one time, whether you're holding the tab in your hands on resting it in a case.

Sony Xperia Tablet Z: Camera

Along with a front-facing 2MP camera, the Xperia Tablet Z sports a rear-facing 8MP camera. The camera uses a similar UI to that used on Sony's CyberShot cameras, including the Superior Auto mode. Along with all the usual arty effects, the snappers also offers Sweep Panorama as well a 10fps burst mode.

Samsung Galaxy S4 vs Apple iPhone 5

After months of rumors, Samsung finally took the wraps off its next-generation Galaxy S4 at a huge press event at Radio City Music Hall in New York last night. That location was no coincidence. From its 1.9-GHz quad-core processor to its 13-megapixel camera, the Galaxy S4 is an almost theatrically overblown phone, stuffed to the plastic casing with hardware and features.
But is it good enough to lure Apple fanboys and girls over to Android? We've stacked up specs for the GS4 side by side against the iPhone 5 to help determine which phone is right for you. Comparing Android to iOS is a little like comparing apples to oranges, but as you can see from the specs, it's a pretty close call everywhere else.
When you look at the phones next to one another, one thing's for certain: the Galaxy S4 is a heck of a lot bigger. With a huge 5-inch screen, the Galaxy S4 technically meets our size requirements for a phablet, which we use to describe phones with screen sizes ranging from 5.0 to 6.9 inches. That means it's probably not as comfortable to hold and use the GS4 as it is the 4-inch iPhone 5, especially if you have smaller hands.

But for those who think bigger is better, the Galaxy S4's monster screen is a step up from its predecessor in terms of size and resolution. Coming in at a full 1,920-by-1080 pixels, the GS4's Super AMOLED panel is rich and bright. At 441 pixels per inch, it's also a good deal denser than the iPhone 5's Retina display, which has 326 pixels per inch. On the other hand, Samsung's PenTile pixel arrangement can make things look a little fuzzy, which is sure to turn some people off.
Other specs are more difficult to compare. Qualcomm just confirmed the GS4 will be using its new Snapdragon 600 processor. We got a chance test it at MWC, but can't yet say how it stacks up against Apple's A6 in the iPhone 5. And the GS4's 13-megapixel camera has lots of crazy features, like the ability to record from both the front and rear cameras at the same time. But recent experience with phones like the LG Optimus G for Sprint has shown us that more megapixels don't necessarily equal better images. The iPhone 5 remains one of our favorite camera phones, so it'll be interesting to see how the GS4 compares.

The biggest difference is that the Galaxy S4 uses the latest version of Android (4.2.2; Jelly Bean), while the iPhone 5 uses iOS 6.1.2. iOS is an easier operating system to learn and use, especially for beginners, and the Apple App Store is still unsurpassed in terms of number of apps available and quality. But the Google Play store is nipping at its heels, and Android features a much more customizable interface for advanced users, which lets you configure your phone exactly how you want it.
There's still no price or release date for the Galaxy S4, but it will be available on all four major U.S. Carriers, as well as Cricket and U.S. Cellular. That means it'll be easier to get than the iPhone 5. But only time will tell if it will be better. For much review see source

Amazon Kindle Fire HD shortreview

Plus

  • Sharp, warm screen
  • Unmatched media library
  • Highly streamlined UI

Minus

  • Online stores are sluggish
  • Lack of core tablet functionality
  • Poor app store
Starting from just £159, and offering a 7-inch HD display and a 1.2GHz dual-core CPU, the Amazon Kindle Fire HD appears to offer great value for money.
But it also needs to offer a stand-alone tablet experience that's capable of matching - or even surpassing - its illustrious rivals.


The Amazon Kindle Fire HD certainly matches the Nexus 7 in terms of price and raw hardware, and it comfortably trumps the iPad mini on price and screen resolution.
But, as we've come to realise, Apple's dominance in the tablet market has been built on strong design, coupled with a peerless content ecosystem and a super-slick UI.
Amazon Kindle Fire HD review
The Amazon Kindle Fire HD may be cheap, but ultimately it will still need to embrace all three of these key elements if it's to succeed.
If you still think of Amazon Kindles as those little monochrome holiday companions, then you should know that the Amazon Kindle Fire HD is a completely different beast.
Rather than focusing on the very specific job of downloading and reading electronic books, this is an all-purpose tablet that acts as a window onto Amazon's wider multimedia world - films, music, apps and games are all included in the Kindle Fire HD's remit.
With that in mind, the Amazon Kindle Fire HD is a much simpler, purer design than the original Kindle.
The emphasis here is on the screen first and foremost, with the only hardware controls coming in the shape of some weedy and difficult-to-locate volume and power buttons on top of the device, right alongside its 3.5mm headphone jack.
The lack of a fixed home key adds to that minimalistic vibe (we'll discuss the effect that has on usability later). The only detail on the front of the device is a 1.3-megapixel camera for video calls - there's no rear-mounted camera here.
Despite that impossibly cheap price point, the Amazon Kindle Fire HD doesn't feel like a cheap device. It's solid in the hand, with none of the creak you find in many budget Android tablets.
There's a nice contrast between the Amazon Kindle Fire HD's smooth, glass front and its grippy matte back. It's quietly pleasing from a tactile perspective, even though it lacks the sheer machined precision and premium feel of Apple's tablets.
