This is also true in Ubuntu's Unity, but after trying to use it, a minor issue drove my crazy: if you switch to one that isn't open it will open the application. So if I accidentally Super-4'd (which I didn't think I did, but after trying to use Unity for a while, I'd do it at least several times a day), it would start whatever the 4th application was. And then you have to deal with it showing up a fraction of a second later. I don't want switching and starting applications to be the same action, because switching should _always_ be extremely fast. If there was a way to make it only switch if it was open, then this would be a viable option for at least my workflow.
