I think in your case it would be better to learn a traditional keyboard layout. There's way more training material and the fingering is a simpler (fewer choices). It also lets you just go to some other place and play the piano there (I think this is the main reason Janko didn't catch on). I think Janko might be a good first keyboard layout for a guitarist or other stringed instrument player.
