I went to the auto show here in Charlotte and over at the Nissan display they had 4 or 5 iMacs but I didn't see any keyboards or mice near them. I looked at the screen and decided to touch it and then I saw the mouse move! I was able to scroll around and double tap on the screen pretty much everything I would expect to be able to do with a touch screen. Upon closer inspection I noticed a lip maybe 1/32" thick that looked like some sort of overlay on the original screen but I didn't see any wires hidden anywhere. It was a very professional job whoever did it. I was really surprized to see this but wanted to know if any of you know about touch screen iMacs. Personally I like having a mouse but this was kind of cool.
