We're not entirely sure if this is called the new Nexus 7 or the Nexus 7 2. Whatever you want to call it, Google's latest tablet is now available to buy in the UK. For the record, Google just refers to it as 'Nexus 7'.Head over to the Google Play store and you'll find stock there for £199 (16GB model) or £239 (32GB). It's a bit up on the original Nexus 7 price-wise, but it does have a few added features to tempt you in. It is slimmer, packs a 1920 x 1200 full HD screen and five-megapixel rear camera, with the tablet also running Android 4.3 out of the box. So perhaps worth the extra few quid.Delivery time is down as one to two days, so it seems that stock levels are still pretty strong. That might change though, so if you want one, you might not want to hang about.It isn't the only Nexus 7 launch for the UK though. This Wi-Fi model will be followed by a 4G version next month. Yes, with all of our networks either running or planning 4G services right now, 4G hardware should be in plentiful supply for the rest of the year. In the case of the Nexus 7, O2 has announced it will have stock of the 4G model for £320 from 13 September. That certainly is a step up in price - and doesn't include a 4G SIM-only deal. So not cheap, but if you want to be the one streaming movies on a larger screen and downloading music in seconds on the train platform in the morning, you might be happy to pay up.
