Ultra-mobile PC (UMPC), What happened?

What ever happened to all the buzz that MS generated with the Ultra-Mobile PC's? OQO has been around for a while. In fact they have recently released a new version of their UMPC, which is pretty impresive - listening OQO, my address is on the right if you want to throw one in the mail to me. A better priced, but not as impressive UPMC can be found over at Windows Marketplace. I think the key to these things is to have a qwerty keyboard.

If OQO could lower their price and increase its size by a bit, I think they would have a winner.

So much buzz, so little results.
