There are Wiimote peripherals. And then there is the Type Pad Pro.
Attaching to the Nyko Wand (the Wiimote is semi-incompatible because it lacks Nyko's proprietary Trans-Port Technology), the Type Pad Pro transforms an ordinary Nintendo controller into a testicularly spaceshippy full QWERTY keyboard. Through Trans-Port communication, the A and B buttons on the Wand are relocated to the Type Pad while the pad itself integrates with the Wii through a wireless USB dongle. (Yeah, it's a tad confusing. Basically, the pad is incapable of piggybacking its signal onto the Wand's.)
