Now that I have 3.1, I've been plugging the A500 into my 55" LCD occassionally and plugged in my IOGear wireless keyboard/trackball into the USB. The keyboard and trackball work fine from across the room, but the problem is the bottom bar of the screen with the back button and the home button doesn't show on the big screen. I can't find any keys on the keyboard the perform the back function or home. Anyone else run into this? I've tried all zoom and aspect ratios on the set. I just watched a moved from the A500 and the picture is pretty crisp but a bit darker than it should be. Still amazing considering the source.
