I've used Dropbox to carry out projects across a variety of working environments. From Educational (grad school), personal projects like multi-media or family sharing and also in my work.
Dropbox is an efficient and useful way to move files between multiple devices. The syncing is quick and the notifications are super helpful.
Another great thing about Dropbox is that I know my data is double-baked up in their cloud. It isn't my only point of backup, but at the very least I know I'm not going to lose a file if it is in the dropbox and my laptop get stolen or some other malady.
I've shared files with countless people at this point using folders on dropbox. No other product delivers as simply and nicely as this for file sharing.
