My only concern is that the buttons look too
small, and it seems like it will be awkward to
hit the right one and not the adjacent one.
Especially if one wanted to have a 4-way cursor
with the activate button in the middle, I would
think you'd be constantly hitting the activate
button instead of a direction button. I'd really
appreciate this kind of information.

Also, Do you have total control of the layout of
the buttons? (pixel by pixel) I assume you can
label buttons with text as well as a preset
library of symbols, correct?
