"The real disappointment is the fact that the device is locked down and we'll never get the chance to use it to innovate the way we interact with our real computers."

It's not a computer, though; it's a device. Apple doesn't want you to interact with it like a real computer.

It's disappointing but if you wait someone will come out with a computer that size and you'll get all of the interactivity you want from it. Hell, Dell has one in the wings.
