There's also a gyroscope, which the iPhone and iPod Touch also have. Mr. Jobs says the iPad 2 will have the same battery life as the first version, but will be 33 percent thinner. It is 13 mm thick to 8.8 mm thick, which is .5 mm thinner than an iPhone4.
It's lighter too than the original iPad -- 1.3 pounds, down from 1.5.
The new iPad is a little rounder. And it comes in two colors. "We'll be shipping white from day one," he says, referring to the elusive white iPhone.
