I'd like to see them license the Optimus technology (

so they can make a keyboard that switches from a Mac OS X Leopard Layout to a Windows Vista Layout when using Boot Camp. You could also alter the settings in Preferences so it changes when you launch a certain application so Final Cut Pro would trigger the FCP Shortcuts and so on.
It would be as expensive as the war against Iraq but I'd buy one
