Dropbox is great and I use it all the time for personal use to share static files with friends like pictures, videos, or documents... however I will never use it for anything serious to do with my work because of two really big problems.

1 - Doesn't use static address' by default. With other services like Google Drive each file is given an ID and when that file is share is uses that ID to share it. This means that wherever I put that file, whoever I transfer it to, even if I change the title the URL to that file stays the same. Not true for dropbox. I don't know if there is an option for this but it's not worth the hassel to find out.

2 - Editing a document almost always causes a problem. With Google Docs or Microsoft One drive the docs that you collaborate on are updated in real time and are never in conflict with one another. The problem with a 3rd party solution like dropbox is that it can't update in realtime which means that if 2 people are working on separate computer there are 2 docs created. Then the other machines have to try to integrate the docs themselves. With 2-3 people this usually works alright but when 5 people are working simultaneously on the same doc someone's work usually goes missing.

Also for personal accounts 100GB = 99$ a year vs Google Drive 100GB = 24$ a year...

I have 23gb for free though so I don't complain ;)

Google Drive would be worthwhile as a service on its own, yet its ability to connect with so many other web applications is simply brilliant. First, connecting additional applications to Google Drive makes it more of an immediate destination when I jump onto the web. Second and even more importantly, it increases the very potential and collaborative uses of these additional applications. Many applications have only been able to realize their true power because of it. Go to the Chrome Web Store on click on the tab dedicated to Google Drive applications. You will be blown away.

I use many online storage services, but Google Drive is the one I'm currently using the most. Especially since their recently announced price decreases, a TB of storage is not very cheap. They also have the best integration across services...if you are a Google services user, which I am. Had some issues recently with large files crashing the desktop app on the Mac, but it seems to have been fixed as I'm not experiencing it anymore.

I use many online storage services. While Dropbox is not my main one I use, it is reliable and easy to use. I mainly use it because several companies integrate automatically with Dropbox for automatic delivery of products, like eBooks. (e.g. O'Reilly, and Pragmatic Programmers). But, they charge a premium for extra storage so I just use the free service.

I use Dropbox both as a user and as a developer. Their products are awesome, fast, and super-great all around. The same go for their APIs — the Datastore API gives you real-time sync, for free, in a few minutes. I haven't found anyone to beat them on either side so far.
