The New Apple Keyboard

As long as they're new, probably no, though all it takes is a driver...

I don't know why apple insist on not being compatible. I guess by now it's more of a trademark, though I always thought it's a weird decision. 

Maybe making the switch to using an apple is the best idea for you, if you really want to keyboard.  It's supposed to be a phenomenal machine. 

Yes you can, I'm actually typing on one of these new shiny slim keyboards on a PC right now, and it works flawessly (the special function keys such as eject or the new media keys don't work as on a Mac, but as F-keys as on any PC keyboard).

You don't need a special driver, by the way, just plug and type.
