Has anyone tried using a Macbook Air?

I am thinking about getting a new comp to run Pure Music and my iTunes library. I realize that Mac Mini's seem to be the de facto standard for this in the Apple realm, but it seems to me that a Macbook Air might be better with its built in display, keyboard and input device. It would unclutter the shelf considerably to avoid a separate monitor, etc. Has anyone got any experience with such a setup?
