Say goodbye to the confusion.
I can’t tell you how many times I’ve been working on something from home but wanted to finish the document at school. I’d save the document to a flash drive and also to a folder in My Documents (I have this phobia that I’ll lose the flash drive, it will get crushed in my bag, or that something like this will happen causing me to lose all that hard work). Well, I’d take the flash drive to school, open and work on the document, and save it again on the flash drive. After doing this a few times, I realize that I now have several copies of the same document in varying degrees of completion. It was time consuming to figure out which was the version that I needed and where exactly it was located. OR I simply left my flash drive at home. AHHHHH!!!
There’s a better way. 
Google offers Web-based word processor, spreadsheet, presentation, and form applications that can be created and edited online. You can also upload documents that you’ve already created to the site. This essentially creates an online “My Documents” that can be accessed anywhere you can access Google. The really cool part is that you can easily collaborate on projects through Google Docs. By adding another user as a contributor, or sharing the document, both of you can work on the document without creating dozens of copies like you would through sharing the document through attachments. Also, the application saves a history of changes that the document goes through so that your work is never lost! As an English teacher, I can definitely see the benefits of using this application for editing and assessing students’ papers. It would also be great to no longer hear the excuse, “My disk is messed up and won’t open my paper!”
Oh, and I forgot to mention the best part: it’s FREE!!
