Something like the Dell 11z or Acer 1410 but in a tablet form instead of notebook form. The Archos 9 is close, but it appears to be under-powered for the task, and early reports are that it struggles with some video files.
Oh, and please get it to market before Apple shows up and ruins the show with their hype.
