I was just sitting here lavishing in the "three monitors of it all". I can truly say that the decision (well, not really a decision as Jeff absolutely insisted) to get a third monitor, specifically a Dell 20", has truly changed my work life. You can not have too much workspace until the monitors completely fill your field of vision.
(Forgive the silly theme and lack of wallpaper...the book editors require a certain Windows theme)
I can absolutely see myself getting forth monitor, and either mounting it to the far right or possibly above the center. The amount of time I'm saving by not Alt-Tabbing during a task is significant.
Window management was taking up a lot my time - I had no idea until I had so much desktop space how much time I was spending just resizing windows. Not moving them around as much as moving them out of the way of others.
When you've got another monitor you can dedicate it to a single task. Right now I'm working on a book, so I've got a VM on one screen, Visual Studio on another, and Explorer on a third. For me, it comes down to this - turning my head is way easier than Alt-Tab.
I never would have believed it until I tried it. I encourage you to look at 2 monitors if you have one or 3 if you have two. With 20" flat panels going for $300, now's the time.
I was using a simple Three Monitor setup in December of 2003, but it never quite took off for me for a couple of reasons:
And remember, when you go Multiple Monitor, you need to get Ultramon.
