Up on stage here in San Fran at Google's Android event, Hugo Barra has been busy announcing the new Nexus 7 tablet, as well as Android 4.3 Jelly Bean. Which we'll talk about in a moment. He also broke some excellent news about a 4G LTE model of the new Nexus 7. As we all know, the slate has leaked all month long and nothing is a surprise. We knew 4G LTE was coming, but not to the extent he just announced.
