Got one of these. Backlight isn't very bright, which is especially obvious on a screen this big - yea, it feels much much bigger than a 7" widescreen.
800x600 is good and easy to get 1:1 pixel mapping, no messing with 800x480 and all that.
Auto-switch-on can be done via the service menu, just like other Lilluputs.
I really really wish that did a 809GL-80NP with transflective or TMR technology.
