Whoa that's pretty cool!
I wouldn't do that to my computer, but I remember needing a control key close to the space bar when I first switched to Mac. I don't remember what I need it for anymore though, since I learned to live without it.
My Thinkpad's keys are backwards to me. But it's easy when trying to turn the backlight down when it's dark. Just the 2 keys on the opposite sides of the keyboard...
