Maybe everybody else already knows this, but I just figured it out not long ago. I hate saving things to a physical device, and then carrying that physical device around with me, just so I can access it if I want to. There are always little compatibility issues that come up, and then maybe I want to write something but I don't have my flash drive... If I'm ever writing a short story to be submitted on a website somewhere, I use my account to store it online. I just start a new email to myself, write my story as the text of the message, and save it as a draft. I can access it from anywhere, from anyone's computer, and work on it any time I have a yen to. The same thing works for photos I may want to edit, as well.
