Google nexus 7 new contestant for IPhone

Inside the Google Nexus 7 is a quad-core Tegra 3 processor packing a 12-core GPU and 1GB of on-board RAM. This, combined with some clever under-the-hood streamlining, means a buttery-smooth performance (pun intended, see below).Its operating system is Android Jelly Bean

Google's tablet runs Google's latest operating system:Android 4.1, aka Jelly Bean. It also benefits from the very polished "Project Butter" user interface technology, which is much smoother than previous Androids or Amazon's forked version of the OS, and it's the first Android tablet to ship with Chrome as its default browser.

There's also a big camera improvement, a whole host of browser tweaks and some clever voice recognition upgrades... in short, a lot of worthwhile reasons to check out the first Android Jelly Bean device.

The Nexus 7 is 198.5 x 120 x 10.45mm. It's considerably lighter than an iPad, and lighter even than a Kindle Fire: at just 340g, the Nexus 7 is the weight of a fairly slim book.

The Nexus 7 display is a seven-inch, 1280x800 IPS display, and you can choose between 8GB and 16GB versions.

There's integrated Wi-Fi but no 3G or 4G, a front-facing camera and a 4,325mAh battery that Google says is good for 8 hours of "active use".

There's also no microSD card slot, so you're limited massively if you're one of those that loves HD movies.

The Nexus 7 tablet includes a microphone, Bluetooth, NFC for Android Beam, an accelerometer, magnetometer, GPS and gyroscope, and the built-in Wi-Fi supports 802.11b, g and n.
