Not for show on any of the stands but when I saw Hugo he gave me a quick look at the OQO 02.
The unit he was sporting had the extended battery fitted and this gives it ~5 hours battery life. The display is a bright, clear and readable 5" with 800x480 native resolution. It was the model with the 1.5GHz processor and was running Windows XP Tablet Edition. The same unit is also available with Windows Vista pre-installed.
The slide out thumb board is quite usable.
Another cool feature is the two scroll bars on the edge of the screen.
Dragging on these will scroll the active window.
Quite a functional little device.
