That video was really awesome. Reminded me of the 24th century!
This has been on the Net for a few days, so it might be old news to some, but I thought the demo video was pretty impressive.
As for the "Tablet Mac" and the statement that Apple has patented the technology, well, I have no idea if that statement is true or not.
Just thought the demo was a great example of what could be a new potential user interface ala Minority Report.
