Agreeing that Dropbox rocks. I use it to share PDF's between computers so I can read them easily anywhere. I have code in there that I need between PC's that isn't on some kind of revision control yet, and finally, I backup my all my code using rdiff-backup which just crons it to my Dropbox every few days. I love it, and the free 2gb is awesome.
