CincyJim,
Running a poll on a mac site about the size of monitors will never be as important as say global warming or third world poverty. But sometimes you have to let your hair down a little.
I've always imagined that fellow MacOsX users would have a preference for big monitors. The poll suggests I am wrong.
BTW, I would personally like 20" displays to rule the world. One would be preferable to Dubya.
