The uDraw Gametablet is intended for casual gamers, majorly for children involving drawing games but possible for adults as well. You put your wiimote into the slot, which then device can connect. Off course you don't get just the device, but a software titled uDraw Studio as well for simplified drawing.
There are 2 titles to come that support this device which is Dood's Big Adventure, and Pictionary. It prices around $70. Cannot be comparable to a Wacom Bamboo, but certainly good for young talents to just mess around and explore their creativity.
