I looked at the keyboard and thought wow what a good looking notebook almost looks like a Macbook keyboard! Then I realized... oh wait that is a Macbook keyboard complete with command keys and system shortcuts in the top row.
It's not even that, it's a rubber keyboard protector. It's just a mock up.
The actual computer driving the display is probably in the pedestal. I was actually wondering at first why there was a glass case around it, but it's almost certainly so that you don't try to pick it up :-) When I worked for a hardware company we did the same thing at shows all the time.
