How I Use It
I use it professionally and with other teachers. I do not teach students to use it (yet), because I am at the elementary level and many of our students have limited access to Internet at home which means we do not often have a need for this type of program.
I LOVE dropbox and recommend it often. It is very intuitive and easy to use. It is just like taking all of your folders on the computer and putting them online so you can find and access them anywhere. It makes retrieving previous versions or lost files a breeze. It makes sharing files easy, even with people who do not have dropbox. I have used this on Macs, PCs and iPhone and iPads with ZERO problems.
