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'.
