I didn't get why Dropbox was so popular when I was using it the same way you are right now. Okay, it's a convenient way to make backups, but so what?

Then I started using it for sharing. Man, it's magic - I've never had it be so painless to share things. I can put a folder in my dropbox, share it to a few emails, and then everyone just has it later in the day. Man, that's cool. I can also create unlimited of those folders easily to control who gets what documents/files. It's a bloody miracle, Dropbox is. The backup feature is really second fiddle to sharing, it's just to make it useful enough for you to try it before you need to share, so that you discover sharing and fall in love with the product.
