Dropbox - 3GB of free online storage

Dropbox is a neat online storage service. You can store 2GB of files with no charge, and if you sign up through my referral link, you get an additional 250MB for a total of 2.25GB. And, by completing a few simple steps, you can get over 3GB in total of free space (Twitter and Facebook accounts required).  Also, you can get up to 8GB of space by referring your friends or up to 16GB by registering your .edu e-mail address.

What can you do with this, you might ask.  Well think of it as a USB stick that you don't have to carry around, don't have to worry about losing, and can share with anyone in the world.
