Does anyone have a preference for the buttons?

Front panel:

Rotate knob left: Rotate piece left.
Rotate knob right: Rotate piece right.
Press knob: Drop piece.
Up button: Move piece up.
Down button: Move piece down.
Right button: Drop piece.
Left button: nothing.

Rio remote:

Volume up/down: Rotate piece.
Menu-OK/Hush: Move piece up/down.
Rew/Info: Also rotate piece.
FF/Visual: Also move piece up/down.
Cancel/0/Search/Sound: Drop piece.

This scheme allows for you to have the rotation and movement be on whichever side of each other that's most comfortable. It allows either one-handed or two-handed play. And the "Drop" buttons are within easy reach of every other button.
