As some one else had already said, Dropbox is non-intrusive. It's a stand-alone product that, by doing so, offers incredible flexibility. The differentiating factor is that, unlike other Cloud Services, it doesn't want to get in your way. It doesn't want to force anything on you. It just wants to make you do what you already want to do, better (sharing files). Google Drive and other cloud solutions have big, overarching ideas. That's one of the reasons why it took Google Drive so long to get out to the public. From what I've read, there was a whole internal political controversy about how it should be implemented with respect to the entire Google bouquet (or current lack thereof). That being said, Dropbox will need to work hard to push the industry of cloud servicing into a new direction to compete with Google, which will be quickly adapting to eventually outpace the startup.
