My Take
Even though my students are older, they are always losing things. They can't find their flash drive; their computer died. There is always an excuse. But with Dropbox, the file is saved on the cloud, so there are no excuses.
How I Use It
I make sure my students save their papers to the cloud. Files saved on school computers get deleted as soon as they log off. But by using Dropbox, students can access their files from school or home computers, so it makes it incredibly convenient.
