Microsoft Vista keyboard?

I spotted a "Vista compatable" keyboard in K-Mart the other day, which set me thinking... what would a Vista keyboard actually do that a "non-Vista" keyboard can't? Then I Googled for "Microsoft Keyboard Vista" and found this ad from Microsoft (Google Cache). What the? "Designed to make it easier than ever to control PC media from your desk, your lap–or even from the comfort of your couch". So… if I use this keyboard's Play button to try and play media that Vista's DRM system thinks I shouldn't be playing, does it administer an electric shock? What if I have the keyboard in my lap :-D  Ouch! No so comfortable now… Thanks, Microsoft, but … ahem, no thanks!
