RND: Powre button plus middle button takes a screenshot.
If you are you are using a TouchPad and are not using a wireless keyboard and teh TouchStone you are missing out. So awesome. [If you are not using a bluetooth keyboard you should at least be using the keyboard mod that puts arrow keys on the virtual keyboard to move around with. Makes the TP much less painful.]
I wish there were more themes for the TouchPad. There is one called Glass but it's not very different and it doesn't look like many folks are making them. If I find out how, will you take a shot at making one?
The app catalog is still pretty weak but the homebrew market (preware) seems to be picking up.
