yeah i would say move the buttons up a bit, cos you don't seem to have a lot of room there to rest your palm..
I originally was gonna have a ENTER, EXIT, PAUSE butons. I then found out ENTER can be used on many Front ends with P1 button. But i went and drilled the holes and remembered afterwards. Opps.
Still, I will probably change the Enter button to something else, maybe tilde (for the volume etc).
