I have a huge Apple Two Page Display that I used for music typesetting until it started to get jittery all over the screen. Not the slow waving that is interference (I had another color monitor too but moving them a little farther apart cured that). A 17in regular monitor is just not big enough.

I had to stop using it because of the jitters (anyone know how to fix it?) but it was a great, very clear and crisp monitor.

The darn thing weighs 70 lbs and is so big I couldn't fit it through the (admittedly narrow) door of my office building.

Also it uses the funniest looking plug (the famous 13W3) ever. I think it's a rebadged Sun workstation monitor.
