To have that much device memory, here are some heavy install applications you can now have on your tablet.

Quackle. An excellent Scrabble game. I think it's like a 110 meg download. I've made a touchscreen keyboard for this if you need it.

Kchmviewer. The best book reader on the N800 by far. I think it's a 70 meg download.

Scid. A super rich chess app with an insane amount of options that can be customized. I believe it's around a 60 meg install.

The best that I can think of though is to decompress Qole's Easy Debian image onto your flash memory.

Anyway, thanks for sharing this.

Oh, and change your icons chief. The default graphics for them are so 2007.
