to get a lot thinner—yet still be super sturdy

Camera[s]:
When I met with HP earlier this month to get up-close and personal with the new TouchPad (it took all night to convince my iPad that me and the TouchPad are, for now, just friends), HP said they only put one front-facing camera on the device because they could not imagine anyone holding up their 9.7-inch device and filming with it. I cannot tell you how many times I wished my iPad had cameras on the front and back. Of course I'd be happy to hold it up and film with it. Herve Leger V-Neck I fully expect Apple to put cameras on both sides of the iPad 2.
Faster:
Apple doesn't talk very much about the raw power behind its home-grown A4 chip, but I'm sure Apple wants to crank it up a bit. In fact, with a much higher-screen resolutions, I don't think Apple has any choice. All the subsystem specs should go up. In fact, I would not be surprised if Apple drops the lower storage option (16 GB) on the iPad 2 and adds a new higher-end one: 128 GB.
Thinner:
If you haven't spent any time with the 4th generation iPod touch, then you're missing out. It is impossibly thin and powerful, plus it has a Retina Display and two cameras, which simply proves that Apple can squeeze a whole lot into a very tiny package. Herve Leger Online The iPad 2's screen should be no smaller than the first generation one, but I do expect it to get a lot thinner—yet still be super sturdy.
