I use it on my mac and windows very vividly, when I edit text documents I tend to save them vigorously in a public folder, and the files get automatically pushed into the cloud once saved. I do this with any web pages I'm working on or images so I can see how a browser renders it from a source, this way I can work on a web page from all perspectives. Desktop and mobile and it's really handy. It beats setting up a web server for small HTML/CSS files.
TLDR; So a selling point about the product is that any file modifications saved, is synced with the cloud file!
