I was real let down by the IPad 2, the most useful feature they could have added was a usb port. Second thing i would have like to have seen was a barometer/altimeter for accurate elevation estimates to supplement the GPS. As a geologist this would have been an awesome feature. Id have an accurate GPS for the field, where I could store geologic maps and view satellite images.
So what they made it thinner. The only real improvement is processor speed and whats the use in that when you didn't really add any new capabilities. They should have worked for another few months and made a better more capable product. The world didn't need this IPad.
end rant
