Thanko has rolled out a case with built in keyboard for the iPad. This case is compatible with only iPad 2 and is made from fake leather. Why? To keep the prices as low as possible. Thanko is currently selling it in Japan for mere 100 dollars, which is pretty cheap by Japanese standards.
The highlight of the case is its Bluetooth keyboard which can be useful if you wanted to do some heavy text entry into the iPad. The reviews of it indicate poor battery life rutimes, and thus we would instead go for something like Belkin keyboard folio or the keyboard case from Sena.
