The Android 3.0 tablet..no buttons.

 

 -- Just hours after Google unwrapped the newest version of its smartphone operating system, Android head Andy Rubin gave a peek at the next major release, which will cater to tablets.
At the D: Dive Into Mobile conference kickoff event Monday night, Rubin removed a fabric case from his bag and unzipped it to unveil a black hunk of plastic.
"This isn't due out for a while," Rubin began.
The device, he explained, is a tablet computer that Google is working on with Motorola.
The hardware along with the software it was running bear resemblances to Apple's iPad. Many electronics makers are working on Android tablets with screens that measure 7 inches diagonally. The iPad has a 9.7-inch display, and this mystery device looked to the naked eye about that size.
Notably, the prototype tablet lacks the signature four buttons used to navigate the Android system. This is on purpose, Rubin said.
