If it could be of any support, I can report that the keyboard is working good on Win Mobile. (and probably this is the very first time an app is working better in Win Mobile than any other platform :)
still don't see full picture how TIC will work on mobile
have two variants, TIC looks like on PC but with custom touch keyboard and you can make a game even on tablet/phone or just like an app to open .tic files and play them with virtual gamepad (not sure that anyone would want to have coding on touch device).
