The black looks WAY nicer. The trackball graphics at first seemed out of place, but after your close-up with 'splanation, much better. Dunno how much of a pain in the ass this might be, but perhaps move the trackball graphic a touch to the right, round it off (instead of the rectangle) and perhaps try one of those "tore a hole in this, and look what's underneath" kind of things. Did that make sense?
Also, is orange the color of your t-molding? If not, I'd play around with some colors for that colored edge. The orange looks....um.....something about it is saying "I'm not QUITE right".....mebbe try different shading for the orange, or different color altogether, or perhaps a gradient of red/orange/yellow ala flames on a car.
At first, I thought the rectangles surrounding the controls was screaming "I'M A NINTENTO GAMEPAD!", but I REALLY like the newer (read: sweeter) shape/coloring.
Excellent job for a one-handed bandit
