Ever since my second "real" programming job, when I managed to sweet talk my boss into getting what I wanted hardware wise, I've used two monitors.
Mostly that means one monitor with the editor and version control GUI, and one monitor with the "other" program of the moment, be that a debugger, browser for testing, email or whatever.
I've become so accustomed to it that I find I get much less done now without it, which is probably also why I find I do very little actual coding at conference with just my laptop (it could also be that I just enjoy the chance to talk to people, or a bit of both).
But until today, when I realised that I'm currently sitting EXACTLY between the two screens, I never really though about which SIDE of the two monitors I should have the editor on, and which I should have the other program on.
I wonder if there's any left-brain vs right-brain effects that might kick in and impact the quality or quantity of code/work generated...
Does anyone use a double monitor setup? If so, what do you put on which side?
