Google's ATAP (Advanced Technology and Projects) team, not to be confused with the Arkansas Taxpayer Access Point (ATAP) group, have stepped up their design game.

The Project Tango tablet is far more polished than the Project Tango phone. The thicker portion of the tablet allows room for the additional cameras, but slims down to a more typical tablet thickness.

From Google: "We also use the unique design to guide the fingers away from the camera. Given that we use the cameras for unique user experiences, it may not be obvious to the user that they are blocking them like you would when using a picture-taking app."

The new design also includes a non-standard dock connector that allows for 12 V high-speed charging and USB 3.0.
