I shifted from 1024x768 to 1280x1024 resolution. Now I have to get all the fonts resized in all the apps to something I can read all day long without going blind. The flat panel display sat on the floor overnight. Wish I had money, space, time, and air conditioning for a work machine and a play machine to try some cutting edge stuff, and another play machine for games. It seems to me that both are development models for extraverts - people who get energy from being with other people.
Extraverts like to think out loud, i.e., the bazaar.
Introverts prefer to work it all out privately before presenting publically, i.e., the cathedral. I have done some of the two person, one terminal work for debugging sysadmin problems. It is effective, intense, and draining. I think three hours a day is about I could stand without wearing out. I wonder how this works for the general programmer population.
