Google Docs

This is a great tool because of the convenience of it. It allows you to make documents on the web, not have to purchase the expensive programs, and allows for you to access it on the web from most computing devices. I think if I would have known about this when I was in college it would have saved my back a lot because I carried my laptop around with me everywhere since I was a smarty and would loose my flash drives so much and the files I made/used were generally too large to email.
