Well if you attach a keyboard to Windows it just works. Even an Apple keyboard. What doesn't are things like the media keys and they DO work if you have Apple's own keyboard drivers which are inside Boot Camp instead of being freely available. I don't understand why Apple would make people's lives awkward like that.

Or why with the Apple LED Cinema Display they would make a monitor that's actually incompatible with their own products - even a very expensive Mac Pro bought a few months before that monitor appeared can't work with it.

Your iPhone apps are vetted principally to ensure they conform to Apple's ideas of what is morally acceptable and acceptable to Apple's own business practices. Nothing to do with stability.
