Mine is lying around, not much used for the past years (somehow I can't get it to run a debian image from SD, so I'm stuck with openwrt... Missing some interesting packages then). What do you use it for?
I managed to install Debian on mine without trouble. I've written a mostly-functional Apple II emulator (minus the graphics modes) and enjoy having an Apple II in my pocket. I also use it to learn Chinese by listening to audiobooks.
What I regret most about the Nanonote is the lack of wifi support (unless one buys an expensive and hard-to-find gizmo). With wifi, it would make a very useful ultraportable computing platform.
