At first I thought "Well, Dropbox storage is 5x as expensive as hard drive space, so what's the point?". What I didn't see was the team use case: It's actually brilliant to have access to every document of all of my colleagues at all times, without saving all that stuff locally, or taking forever sync. This is really amazing.

The problem with our current shared team folders is that you need to make a deliberate effort to share something with the team. That means when you want to pull information from the shared space, you're very likely to get an outdated copy. Thanks to 1.) no storage constraints and 2.) deep OS-integration, all files can actually be always up-to-date with Dropbox Infinite. That really sounds cool.
