James Kendrick points to this Engadget article that talks about a forthcoming X200 Tablet from Lenovo. Rob Bushway had some speculation on the X200 Tablet back in Feb of this year. So maybe we’re getting close.
Lenovo takes a swipe at Air with a spoof commercial:
Yeah, the Lenovo Thinkpad X300 is very nice. I had an opportunity to play with one awhile back. Loved it. It would be even nicer though, if there was a Tablet version. 
Is there any doubt from this picture on Robert Scoble’s blog that Lenovo CEO William Amelio is proud of their forthcoming MID?
