Why? The competitors are better and have more features. SkyDrive integrates tightly with my OneNote, XBox music, Office suite, email and everything else I need. It has features Dropbox doesn't. And it's a better deal.
I don't regret using Dropbox. Not for a second. God knows I've talked them up to all my friends. But performance with them got a bit sketchy and better options are now available.
