I remember seeing this, it is a 3rd party tablet running OS X. I think a touchscreen MBP would make the CNET Front Door etc... and there is nothing of the sort in the tech news.
I susbcribe to the Mac on easysilence video podcast. Their last release was a summary video of Macworld, about halfway through they showed people using a touch screen. At first I thought it was an Apple touch screen, but it appeared to be mounted on a form similar to the Macbook Pro, and it defintely had a series of ports on the side, including an available mini-DVI, leading to my belif that this isnt a clever touchscreen/hub or a touch screen connected to a Macbook Pro, but a full on tablet computer.
Can anyone confirm this?
