If there's a place where Windows has always had an advantage over the Mac, it's in supporting esoteric peripherals. Take the Ergodex DX1. It's a free-form keyboard, basically. You can stick on keys anywhere, in any arbitrary fashion, then map them to keyboard equivalents. Want to arrange them in a grid? You got it. Want them in a semi-circle? Cool. Want them just plopped on there in no particular pattern? That works too. It's a cool idea for people who want to build their own custom key interface, for gaming or just about any other specialized task you can think of.
