A lot of people are asking about tablets, etc. We have a few threads on other ones that just debuted so I made this one as well. It's being previewed now with a release date of March 11.
Main points thus far:
Dual-core A5 processor, which is "up to two times faster".
Same low power consumption as the A4.
The graphics have been improved too. Exact GPU unknown right now. Apple is claiming "nine times faster".
Built-in cameras for photos and video: One for frontal FaceTime videoconferencing and one on the back.
It also has a built-in gyroscope, like the iPhone.
New cases put it to sleep, wake it up, etc.
HDMI out with accessory cable. Supports 1080p.
Ships with iOS 4.3.
Same price at $499.
