I think Linux is used extensively for the hyper-professional stuff, but those programs cost $10,000+ and really aren't meant for consumers.

I haven't done video editing on Linux for awhile, Lightworks is generally pretty ok, but I don't really know of any equivalent to After Effects or Apple Motion available on Linux, at least in the consumer space. I don't really do enough interesting stuff with video for that to bother me but I suspect that could be a blocker for a lot of people.
