I'm bad at Photoshop but you guys get the point, don't you?
I really wish for the 3 user customizable keys, personally I would use the top two buttons for previous/next Space, and the bottom key to switch to my iTunes.
And the trackpad to the right could be used for customizable multitouch gestures, so you can move around spaces easily, scroll with 2 fingers if you have a desktop and not a laptop, etc.
I think it's very important that Apple includes multitouch for desktop users and not just laptop people.
