Sony Xperia Z2 Tablet Sony's previous Xperia Tablet Z was an incredibly slender piece of kit, measuring only 6.9mm thick, but the new model has managed to slice off even more, coming in at only 6.4mm. Its slimness is immediately noticeable when you pick the slate up as it feels like a thin pamphlet. At 426g it's very light as well, which should help make it comfortable to use for longer periods.Design-wise, not much has changed since the previous model. The front is a button-free, all glass design, while the back panel is a wide expanse of matte black plastic, with the minimal Sony branding in the middle. Like its predecessor, the Z2 Tablet is completely waterproof, allowing it to shrug off an errant spilled drink or let you dunk it in the sink to rinse off smeary fingerprint marks.The 10.1-inch display boasts a Full HD resolution, making it well equipped to tackle glossy, high definition shows on Netflix. It's not quite matching the iPad Air's whopping 2048x1536-pixel resolution, although side-by-side, I doubt you'd notice much difference.On the back of the tablet is an 8-megapixel camera which should be at least good enough for some Instagram shots of whatever you've cooked that evening.Stuffed into that skinny frame is a quad-core Qualcomm Snapdragon 801 processor, clocked at an impressive 2.3GHz, backed up by 3GB of RAM.

Weight15.03 oz VS Apple iPad Air The Air is a tangible upgrade over the previous, fourth-generation iPad, no longer in production and so banished to the annals of history. The new iPad slots right in where its predecessor left off, priced at $499 for a lowly 16GB, $599 for 32GB, $699 for 64GB, and $799 for the maximum 128GB configuration. The iPad Air delivers more performance and comparable battery life in an attractive and impossibly thin-and-light package. An improved front-facing camera makes FaceTiming look better, and the Retina Display still looks great.
But, The Touch ID fingerprint scanner, introduced on the iPhone 5S, is sadly absent here, meaning you’ll still have to type in a passcode with every unlock and a password with every purchase. Starting at $499 for 16GB, it’s still expensive compared with the competition. Performance: The iPad Air shares the same processor with Apple’s flagship phone, albeit with a slight bump in clock speed. While the 5S runs at 1.3GHz the Air runs at 1.39GHz. It can achieve this because of the increased space and improved heat dissipation of the Air compared to the much smaller iPhone 5S.
Indeed, before we go into the detail about performance it’s worth noting that the iPad Air manages to keep its cool with consummate ease. Even when running intensive 3D games and apps for hours it barely breaks a sweat and, therefore, neither do your hands.
In practice, the iPad Air is blisteringly fast. Apps open instantly and games like Infinity Blade 3 look sumptuous and run smoothly. The benefits of having a SoC means that the GPU can be used to tackle compute tasks, which makes video editing and compute intensive apps, like AutoCAD, show no hint of slowdown.
The iPad Air performs 59% faster than the iPad 4 in the 3D Mark Ice Storm Unlimited CPU and GPU test and 91% faster in Geekbench 3 tests. The Peacekeeper browser test, which assesses web browsing performance, shows that the Air trounces its predecessor by being more than twice as fast. It's also faster than the stonking Snapdragon 800 processor on the likes of the Sony Xperia Z Ultra and Google Nexus 5. We're talking matter of degrees here, but the difference is there all the same.
Battery life: Battery life on the iPad Air is quoted at "Up to 10 hours of surfing the web on Wi-Fi, watching video, or listening to music". We would say that's actually not a bad estimate, although the drain was closer to 2% every 10 minutes in general use, which equates to around nine hours' use.
Standby time is much, much better though. We found that we could stick the iPad Air in a bag, taking it out for the commute and messing about with on the sofa at home, for at least three days before it began to get low on battery.
In fact, the only real task that killed it was connecting to our amplifier via Wi-Fi while simultaneously streaming music to the same device through Bluetooth. It's doing things like this that make you realise that this is the kind of thing that we envisaged at the turn of the century, a tablet that has the brains and connectivity to do all the tasks we could want.In terms of connectivity, we've already mentioned the excellent Wi-Fi performance (in terms of distance from router, rather than improved speed) through the Multiple In, Multiple Out (MIMO) technology.
4G bands are now covered throughout the globe, and low power Bluetooth is also on board as well, making it an incredibly well-connected device.
The bottom line: Functionally, the iPad Air is nearly identical to last year’s model, offering only faster performance and better video chatting. But factor in design and aesthetics, and the iPad Air is on another planet. It’s the best full-size consumer tablet on the market. Specifications

Weight1 lbs Price:$479.00 VS Samsung Galaxy Note 10.1 The Samsung Galaxy Tab 10.1 2014 is a seriously well-specced Android tablet, with a class leading quad-core processor and a superbly sharp 10-inch display.
Samsung's S Pen stylus feels perfectly at home with this stunning screen, turning the tablet into a sketchpad, a notebook, a virtual scrapbook, and much more beside.The Samsung Galaxy Note 10.1 sports a proven, sensible design, a bevy of useful features, and fast performance. The S Pen Stylus is a unique addition.The 2014 Note 10.1 has a non-removable 8,220mAh battery. That's significantly larger than the 7,000mAh battery of the last model, but it's needed because of the higher-resolution screen.
To give the Samsung Galaxy Note 10.1 2014 more of a chance against its competitors, we turned off most of the Samsung extras, such as the eye-monitoring Smart Stay before setting the tablet to play a looped SD-quality video. It lasts for a fairly impressive 12 hours of video playback.
But, Only a limited number of apps make full use of the S Pen and some of the ones that do can be buggy and confusing. Some S Pen features aren't enabled by default and others don't work properly.
The bottom line: The Samsung Galaxy Note 10.1 is the best Samsung tablet yet. If you can get over its somewhat high price, it's a sound Android tablet investment. Specifications
