As expected, the new tablet is running Android 4.3 Jelly Bean. There's new set of multi-user settings, including restricted profiles for kids, which means you can restrict app content at a user level. Bluetooth Smart, aka Bluetooth Low Energy, support was one of the expected features of Android 4.3. It's joined by OpenGL ES 3.0 support, which Hugo Barra rightly identifies as "a big deal for game developers." NFC is also on board, for those who might want to use Google Wallet with a 7-inch tablet.
Google claims the tablet will offer up to 10 hours of battery life, and that its 1.5GHz processor was 80 per cent faster than the original model. Memory has been doubled to 2GB.
