Dropbox it like it's hot

So I am trying out this app called dropbox that could be pretty sweet. It basically creates a 2gb free folder for you on their server that you can access anywhere. That alone isn't the greatest part, when you install dropbox to your computer(s), it adds a synchronized folder to it. I just installed it on my desktop and put my files for my bioinformatic final in the dropbox and in theory I can goto school, grab the files and work on them, come back here and have them be the current version. It's kinda like a svn repository for whatever you want.
