After much speculation and just about every tiniest detail having leaked in one form or another, Google's latest OEM tablet device is now official. The new Nexus 7 as it is called, much like the last one, is a product with the adage "if it ain't broke, don't fix it" very much in mind.

Inside, manufacturer Asus has included a 1.5GHz quad-core Qualcomm Snapdragon S4 Pro processor, Adreno 320 graphics and 2GB of RAM. The 7-inch screen has had a significant bump in resolution to 1920 x 1200, which represents 323ppi, so should be more crisp than last year's tablet. It is still an IPS LCD panel but shows a 30 per cent wider colour gamut.

Another significant change this time around comes in the form of a rear-facing 5-megapixel camera. Last year's Nexus 7 didn't have one at all. A front-facing 1.2-megapixel camera is included for video calling and the like. And there are stereo speakers this time.

Dual-band Wi-Fi 802.11 a/b/g/n is on board, but there's no ac compatibility this year - that might be something saved over for the next edition. There's also Bluetooth 4.0 and a micro USB port for hooking it up for charging and file transmission. SlimPort support also means you can output video through an adaptor.

The second-generation Nexus 7 measures 114.3 x 200.6 x 7.6mm and its weight is 317.5g. It comes with the very latest version of Android installed - Android 4.3 Jelly Bean, also announced and detailed during Google's announcement event - and all of the associated apps and services.

Pre-orders for the 16GB and 32GB Wi-Fi only versions have been open for over a day now at $229.99 (£195) and $269.99 respectively. And an LTE 4G model will be available on AT&T, T-Mobile and Verizon. It will be shipped unlocked and you can add the SIM later.

Google has confirmed that the new Nexus 7 will also be coming to the UK, Japan, Canada, Germany, France, South Korea, Spain and Australia in the next few weeks.
