Google has my email, Dropbox has my taxes and a few other important documents, wedding photos are also on a family member's computer, and svn / github takes care of my code for work / play.

Nothing else I have is that important. Lots of games and recorded TV shows. Either I already finished it, or I'm probably not going to.

I could loose my desktop or my laptop and only be out time. If both died at once I might loose a few important things, but nothing too life-shattering. In general, I can pick up a brand new computer and be productive by the end of the day.
