I just changed my display setup from a single 28" Hanns-g to two 22" 16:10 Acer X223w screens and am really liking it. I think two smaller screens is better than one big screen for productivity. I was going to buy one more to have a triple setup but didn't know if it was worth it or if it will bother me having a third screen. I don't game anymore, I just do a lot of surfing and schoolwork (programming, database, etc.). I was planning on getting two 24" but almost everything out there is 16:9, which I just cannot stand. The few 24" 16:10 are expensive especially compared to the $132 (tax and shipping included) I paid for these 22" screens.
Anyways just sharing my experience.
