Great system, the synching is fast, and the setup is as easy as installing office. Just login and you're set to go. Great product I install first on every machine.
I love dropbox and how it is integrated into my Max OSX, I use it weekly for sharing, storing and backup projects and files, there's no much to say about dropbox, it does what it says it does, Is easy to use and is great for team work and efforts.
