My experience with Debian Unstable

I ran debian unstable in my desktop for something like ten years, and I had some breakage -- something like a workday of downtime every three months or so. Not that I am complaining too much -- even Ubuntu used to give me half a workday of downtime every dist-upgrade (but I must point that the last three or four ones were flawless) probably due to the half a dozen PPAs I still use.
