The OS2008 backup tool backs up the repository lists now, which is a start. The rest should be possible, my Debian and Ubuntu PCs can do it.

My N800's usage is random. It sat on my desk with a flat battery for a week and a half after upgrading to os2008 since neither of my two most used apps (maemo-mapper, UKMP) would work on it. Now they do it's back in my car where I use it most.

But when not in my car it usually sits on top of my microwave out the way, occasionally being used for Skype or random web browsing.
