I don't think Dropbox has ever tried to compete on price though, have they?

For me, there are two things that make Dropbox a better option than MS/Amazon/Google:

1) It's their core business. You know it's not going to be dropped next week because the side project wasn't popular enough or it's not making enough money.

2) The on iPhone/Mac apps that I use quite often offer a sync option with Dropbox not many sync with other providers.

Ignoring Google and their "empire where the sun always sets," cloud storage is going to become a thing like MP3 players and web browsers -- it's going to become part of the base expectation of having a platform. It's already in Windows, iOS and Android. It's not going away.

Definitely. But so far, Dropbox is faster and has better sharing functionality (e.g. show me a list of folders that I shared, which e.g. Google Drive cannot do).

For business use, the $10 per month is peanuts for a more seamless experience.

Besides that, Dropbox seems to be branching out. There is Carousel, which I like quite much compared to the cl*sterfuck that is Google Plus photos. I can put my photos in regular Dropbox folders, but still have a Flickr-like experience. Also, there is Mailbox.

Of course, they need a better collaborative editing story than 'you can save from Office on Android/iOS to Dropbox'.
