Not sure if you're looking for ideas but connecting USB devices to the N800 seems to be a fairly popular topic and thanks to OS 2008 and some recent developments on the adapter side of things it's easy enough now to be "newbie experience level capable" ;-)

Just a though... great work on the rest of the site though, I'm going to send a link to my Dad so he can learn to get the most out of his N800.

Thanks!
