I prefer 2 17" over 1 30", the divider i find is good, makes a multi-desktop interface, rather then a large desktop. Works wonders in many environments. 1. Programming - Main code in 1 monitor, reference matterial (header file, notes, etc) in the other - Main code in 1 monitor, testing in the other - Main code in 1 monitor, GUI in the other 2. System Admin - Your desktop in 1 monitor, VNC/RDP to server(s) in the other. (or for me AD in 1 90% of the day, my desktop in the other) - Your desktop in 1 monitor, monitoring/management software in the other. (very easy to tell when something breaks, w/o watching 24/7 coz the status is right next to you) 3. Tech Support - Docs/Issue Report in 1 monitor, VNC/RDP to client in the other I work at two different sites, 1 site I have 2 17" monitors, I love it, but unfortunately my boss at the other site has just ordered me a 22" monitor w/o asking me if I want one, so now i'm going from 1 17" to a 22" when i'd rather 2 17" which is cheaper.
