My Take
As a teacher you can save all file types that you want to access at home and in the classroom. You can send any type of file to students, teachers, parents... anyone! Easy to use and has the "drag and drop" functionality. Students can also use this as their file storage, so they don't have to worry about using the same computer, or have the excuse of leaving assignments at home!
How I Use It
One of the first and best cloud based storage applications, dropbox gives you 3 GB of free storage that you can access from anywhere on just about any devise (mind you, you will need to be connected to the internet. You can leave the flash drives at home and access any file type you want through dropbox. Great storage solution.
