As the slate 7 is now readily available for £99, a review which takes this into account is now required. It's firmly into the budget market, undercutting the Nexus 7 significantly. This tablet is now directly competing with Acer Iconia, which has half the memory, and a host of cheap and flimsy Chinese tablets.
The build quality is great; it is very well made, has a pleasant weight and solidity - overall very much a premium feel to it. The screen is perfectly adequate - bright and colourful despite its lower resolution of 1024 x 600. Some fonts do look a little ragged though, for instance the Twitter app is not great.
In operation, it works faultlessly, and the response times and the feel of the interface are excellent - a worry for me as a previous experiment with cheap android tablets ended quickly in significant dissatisfaction. Admittedly, I'm not using it for games, but for use with email, note taking for work, for Kindle reading and for general web browsing it's really a super piece of kit, with no lag at all.. I think the 1 Gb RAM makes all the difference here - playback on YouTube and iplayer are clear and smooth. No problems here. No complaints on battery life either, lasted a couple of days of fairly regular use at work.
Worth noting the SD card slot, giving the ability to expand the memory to 32Gb, and the 3Mp camera on the rear. Both useful additions not present on the Nexus 7. But no GPS and you have to put up with Android 4.1, hardly a huge handicap.
In summary, it's not the absolute best Android tablet you can buy, with the screen in particular being inferior to the Nexus 7. But the price / performance has to be considered, and it makes the Nexus 7 look extremely overpriced. I'm convinced it's the best tablet you can buy for under £100 by a country mile. Buy in complete confidence.
