Here in Dubuque we have hexagon shaped cubicles with five people to a hexagon, and a corner left open so that we can get in in the morning. Anyway, I have a pretty sweet set up, two 22 inch wide screens and a 4 core 8GB RAM computer even though I only run simulations through our 256 core 560GB RAM cluster.
People sometimes ask, "are you twice as productive with two screens?" The answer is obviously, "no", but if I am 5% more productive and that screen only costs 2% of my productivity then it's a good deal. The more important question is, "are you noticeably more productive?" The answer to that is, "yes". After using two screens one just seems so unproductive.
So that's my life 8-10 hours a day 4-5 days a week.
