Quitting programs is a problem. It seems nothing is mapped to the "home" button. The home button is like the tablet's switch button, its brings up alt-tab and stuff. The only way right now is just to keep clicking back until it closes. I usually open a new window, close the old one, then click back. Usually works.

Sadly, most of the apps are for the small screen of the G1, or at least a "tall" screen. Is there some way to flip the orientation, like the xRandR that maemo has?
