I agree, I really enjoy Apple keyboards. Well I don't like the new one, I preferred the white ones with the USB ports on either side.
As for mice, again it depends on what people like and the size of their hands. Personally I hate Apple's mouse, it's too flat. I use a Microsoft IntelliMouse, and it's the best mouse I've used by far.

Similar to mine, only mine hasn't got those weird silver buttons.
