Dropbox vs Google - Modula 4 / Assignment 6

Dropbox and Google Drive are new to me.  What I know about these services is limited to my experience in class and with the modules.  As I read the article, Google Drive VS. Dropbox - In Depth Review, I found the information to be confusing.  I had difficulty determining unique and similar features for comparison.  The text basically just all ran together.  I did derive the overriding feature of the two is the ability to have access to documents on all computers so that editing can be accomplished anywhere.  I feel the best way for me to form an opinion of each service is to just use them.  For me, exploration is the best teacher.
