I’m addicted to dropbox right now. They give you 2gb of free storage space for your files…allowing you to share big files with you friends etc. But, the real kicker for me is the ability to sync your files across several computers and constantly have your work backed up…it’s really awesome. You just have to download their software.
I’m not doing the software/service justice. But check out this link and watch their video demo. Also if you use that link and sign up for their service, they’ll give you another 250mb of free space. (I won’t lie, they’ll do the same for me too!)
I’m a dropbox convert! I love it!
