The Nexus 7 is the first tablet in Google's Nexus line and the first to sport Android 4.1 Jelly Bean.
The device was jointly developed with Asus and Google, and is the world's first 7-inch quad-core tablet. The device will be available through the Google Play store.
"ASUS is very excited about this partnership and the synergy that it brings to the hands of consumers," said Asus chairman Jonney Shih. "We had only four months to build a high-end tablet that could sell at just under US$200. By placing our team of dedicated engineers closer to Google's, we delivered the Nexus 7 in record time."
"I don't think there would have been any other partner that could move that fast. Asus went from zero to a working product in four months," said Andy Rubin, SVP of Mobile and Digital Content at Google. "We wanted to build a tablet that was light and portable enough for users to take their favorite entertainment wherever they go, but still didn't compromise at all on power and performance. Together with ASUS we were able to accomplish that in the Nexus 7. Starting at $199, it will be something everyone can enjoy."
The Nexus 7 has a vibrant 1280x800 HD laminated IPS display, and uses Nvidia's quad-core processor and a 12-core GeForce GPU that delivers stunning graphics. Asus' TruVivid technology improves color clarity and brightness, while Corning FIT glass ensures a scratch resistant and durable display.
Asus says that the Nexus 7 will deliver 9.5 hours of battery life in a slim profile that is just 10.5mm thin and weighs 370g.
Prices are set at $199 for the 8GB version and $249 for the 16GB version. A limited time offer gives the chance for early adopters to avail of $25 in Google Play credit, that can be used to buy movies, books, magazines and other digital media.
