Discovered Dropbox recently and it looks very good. What does it do?
Put your files into your Dropbox on one computer, and they’ll be instantly available on any of your other computers that you’ve installed Dropbox on (Windows, Mac, and Linux too!) Because a copy of your files are stored on Dropbox’s secure servers, you can also access them from any computer or mobile device using the Dropbox website.
Full feature list: https://www.dropbox.com/features (first 2GB of storage free)
