I have taken advantage of Dropbox's cloud sync features quite often. For example, my school's printers are attached to library computers but not my laptop. So I can just log in to Dropbox from a library computer to download and print a file from their web interface. The only real alternative would be to first send myself an email with the file as an attachment, which would require me to have the forethought to send that email from my laptop first, instead of knowing I can print any file I want whenever I want. Also, I often share individual files by using the "Get a public link" feature in Dropbox, and it's comforting to know they can just access those files whenever they want no matter what devices are attached and syncing.
