I love dropbox for my works stuff.
I have a number of folders set up so that if I get a new manual, tech bulletin etc all I do is download it onto my pc, bung it in dropbox and all 4 of the machines I use for work including apple, android and winddows devices all get upadated to the same data.
Great program well worth using.
I'd be realy interested to know whats wrong with it.
