I think it would sell.

The question is whether it could be built! Here's the problem: in a box the size of an iPaq, you have to get a battery almost the same size as the one you'd need to run a ThinkPad.

The PC, even if you shrink it down to the size of an iPaq, still chews power. But if you shrink it down, people expect you to shrink the battery down, too.

A battery the size of an iPaq battery would probably keep the Oqo going for about two hours. Even with an Efficeon.
