I was watching an Apple Web Seminar on Aperture: Streamline your work flow after the shoot", trying to get an idea of Aperture is right for me. About 10 minutes into the 30 minute lecture an Aperture developer says something to the effect of how well Aperture runs on the 30" ACD, but to really get the "true" experience of Aperture you should see it run on dual 30s. He then says that regardless, it's possible to really get a good feel for the workspace on the single display. I thought that was a cute way of saying that Aperture is best with dial 30" displays which in my opinion is not a necessity for all photographers or people using Aperture. But just to kill my curiosity, is anyone using Aperture on say a 20-24" display who is upset about the screen workspace?
