A little late to get in the conversation, but I use 3 21" at work and 2 21" at home. All are widescreen. 3rd is basically for a dashboard so I can monitor all the servers/network at a glance. I never tried anything bigger than 21". Looking at larger ones make me think it would be overkill and hard on the eyes. And my eyes aren't what they used to be to begin with...:smooooth:
