Do you work on different computers? Perhaps you go back and forth between your home computer and your school issued laptop...trying to remember which computer you saved your work on. Ever find that you've left your flash drive behind and don't have access to the documents you need? I've been there myself. Then I discovered Dropbox. With Dropbox, I always have access to my files from any computer I use or even my iPod Touch. This would also be a great tool to introduce your students to that would help them stay organized and always have access to their work. The free account gives you 2 GB of storage space.
