That link I posted above no longer works

so I will try to maintain an up-to-date list of Wireless Keyboards here:
Mice: Apparently DO NOT work.
Wired KB: They ALL should work. All wired ones should adhere to a basic common standard and that driver will be present in the Wii (AFAIK all wired solutions work for the common keys (like QWERTY...., Shift, Backspace etc).....some of the more "esoteric" / "specialist" keys (like "open mail", "next track" etc) may not though)
Wireless KB: Here is a full list of wireless wii keyboards that we know are compatible with the Wii (I think all of these come with their own BT dongles).
