I would also buy it promptly
It is the Android hobby effort I referred. They did not proceed being mindful of patent claim. But that simple keyboard, put together by a kind soul over a lunch break, is usable - like I said with one hand while travelling in rush hour Metro as well. It is raw, basic & unpredictable in a certain way. Since I am desparate for Fitaly layout on the Android, this rough thing is better than the Qwerty. Grateful to the hobbyist, and to you sir - for the response.
