Dropbox - Secure backup, sync and sharing made easy.

I like to use this to store and share files, especially when I’m working on a project and want to make sure that all my colleagues are working on the right version of a file. The free version starts out at 2 gigabytes of storage per person, and you can earn up to a total of 8GB by referring friends, 250 MB per friend. How cool is that!
