The problem with Dropbox is that it is not locally encrypted. This means it will only ever be used for sharing excel spreadsheets at work.

Dropbox has a team of people whose only job it is to write AI software against the data being saved there. They have software agents rummaging through everything you upload (which is maybe not surprising, but also not a service I want to pay for).

I think if someone could combine the sharing aspects of DropBox with some of the more secure cloud backup products (like CrashPlan) they would have a winning business model.

The secret sauce would be figuring out how to do this without becoming a pure infrastructure provider, where the margins are a race to the bottom.
