Not sure about the 16GB, but the 32GB model is available for £149 from O2 shops in store: Nexus 7 32GB WiFi Only Tablet £149.99 instore O2 - Hot UK Deals
Thank s..something's that's confusing me...why some have jelly bean and others have KitKat? The one you linked has jellybean... But KitKat is the new os
Yeah - you'll find more or less as soon as you've finished setting it up - it will download an update to the latest version.
Jelly Bean is an older version of Android. KitKat is the current version, and something sweet/candy beginning with L will be the next If the o2 one has jelly bean it will be an old model, slower cpu, less ram etc, but cheaper.
amazing people are selling the Jellybean for the same price as Kitkat ones.. picked up a 3 day old Nexus 32GB with Wifi (Kitkat) for £115... with original receipt.. thanks all...
