At the moment using two Nokia N900s, with an extra three backup N900s at home.

The active ones are both running CSSU stable, until I sort out what happened to a N900 on Thumb heavily crashing and needing a re-flash. Backupmenu had not been working properly saving for weeks, perhaps due to data corruption..I'm still not sure what went on. So, for now staying in Stable and installing mostly from Extras.
