Google has finally officialy announced its Nexus 7, a Tegra 3 powered 7-inch 1280x800 tablet with latest Android 4.1 Jelly Bean OS. 

As rumoured earlier, Nexus 7 tablet is built by Asustek and feature four CPU and twelve GPU cores (guess Google forgot that Tegra 3 is a 4+1 GPU chip) thanks to Nvidia' Tegra 3 SoC chip as well as 1GB of RAM. It features a 1280x800 IPS back-lit screen covered by scratch resistant Corning glass. The precise dimensions are 198.5x120x10.45mm and according to what we could see during Google I/O it looks like a decent device, design wise. It weighs 390g, so it is relatively light, too.

The rest of the specs include NFC for some fun with new "tap-to-air" and Android Beam features, 1.2-megapixel camera, 802.11bgn WiFi, Bluetooth as well as an accelerometer, GPS, and all other goodies that you would expect from such a tablet. The device will pack a 4325mAh battery that is, according to Google, enough for 300 hours of stand-by, 9 hours of HD playback, or 8 hours of continuous usage. Unfortunately, just like Amazon's Kindle Fire, the Google Nexus 7 tablet also lacks a microSD.

In case you pre-order it now Google will also throw in a 25$ credit for Google Play store and some bonus content, including The Bourne Dominion book, Transformers movie and a bunch of various magazines in order to promote its new Google Play that will include movies, TV series, magazines and, of course, books.

As noted, the new Nexus 7 tablet is already up for pre-order in the USA, Australia, Canada and the UK with a price tag set at US $199 for the 8GB version and US $249 for the 16GB one.
