I tried it once, and decided I would rather have two larger monitors. I use dual 24" on my mac and I love it. (It seemed like I was forced to move my head a lot more with a quad monitor setup - either vertically (cube setup) or horizontally (4 in a row setup), and it wasn't very enjoyable to me.) [Edit: I was using all 20" monitors for my test, and I actually liked 3 monitors more than 4 - there was a logical "main" monitor that way.]
