I finally gave Dropbox a try and it’s awesome ! Dropbox makes syncing files across computers a breeze (Linux, Mac OS X, Windows).
I recommend you check their screencast here to get a better idea of what it does.
By default, you get 2 GB with the free account.
If you are interested in testing it, please use the link below for subscribing : https://www.getdropbox.com/referrals/NTEyMTA5NTc5
For any new user referred by me, both you and I will get an extra 250 MB on our accounts.
