Hmm...user friendly, Man I`ve not thought of that b4. Okie, regarding switching from kb to piano...shouldn`t be a problem if u take note of yr posture and positions...and work those fingers. U can refer to a previous thread regarding correct position and posture in the Piano Forum by Hello...I can`t remember the subject though, I think it`s `...How To Play The Piano Well`.
But remember...too much kb makes yr fingers weak..unless u`re playing it like a piano.
