I enabled OS X's Single Application Mode about three weeks ago and haven't switched back yet. The decision to try it was spurred by more time spent with an iPad. I also tried replacing the mode with Isolator on my work computer, which is looking promising for the more inter-application-focused workflow I need there. It's amazing what a difference either of these approaches makes. Given that this movement is getting coverage in The Economist now, I almost expect Apple to implement something not entirely unlike Isolator for 10.7.
