The same, only better
The iPad 2 is thinner, faster, and includes two cameras, but otherwise, the iPad stays the same: size, price, capacity, and features all carry over.
Oh, except for color. Apple now offers both white and black versions of the iPad 2 in every price. The smallest model is $429, giving you 16GB of storage and a Wi-Fi connection. If you want more storage you can jump up to the 32GB ($599) or 64GB ($699) models.
