I played around a bit with spaces. I guess I had a preconceived notion on how it was supposed to work, but I think I'm missing the point. Maybe it's because I have a 17" monitor. My preconceived notion leads me to believe that on a huge screen, I could divide up the screen into Spaces, confining my work into a section of the monitor. Am I seriously way off here? I set up two spaces, side by side and assigned an application to each, but I don't see the point. Thanks for any explanation.
