Same here. I had some sort of electrical problem with my last computer and lost my hard drive due to it. Unfortunately, my back-up drive was also plugged in at the time and it got fried, as well (really bad luck/timing there).

One of the first thing I did when I got the new computer was to put a symlink to my projects directory in my Dropbox folder, so that all of my projects now get backed up to Dropbox automatically.
