I am a photographer so my workspace currently consists of a 17" Dell (CRT tools monitor) and a 20" ViewSonic (LCD image monitor [calibrated]). Both are set up on a dual monitor configuration.
I will eventually turn the 20" into a tools monitor and pick up a Wacom Cintiq 21UX (

Also, the Mac Cinema Displays are nice so I might have to pick up one of those for myself.
I should also add that CRTs are infinitely better for critical color work. LCDs are brighter and sharper but less color accurate. There are other differences but I don’t recall them at the moment.
