I'm glad to see everybody seems to have 2+ widescreen monitors. Where I work, an amazing number of people work off a single laptop-sized screen all day. I don't understand how they can do it; it makes me wonder if I'm some kind of programmer-'tard who needs special equipment to function. Good to get some affirmation to the contrary.
The equipment is not so important. I have written some great applications hunched over my 9" eeepc. Generally, I use a 24" monitor and happy hacking keyboard, though; which definitely makes things easier. (It also makes it easier to get distracted by HN, though.)
I spent a while coding on a 15" Lenovo laptop and it works because the resolution is 1920 x 1200. I still like to use multiple monitors but it's not really necessary.
Worst coding environment was probably one of those CRT iMac's running OS 8.
I sit in front of my 24" monitor when working in the Flash IDE, Illustrator or PhotoShop; otherwise I prefer working directly on my laptop. I generally just keep an instance of MacVim, a terminal and a browser open; I find myself staying more focused this way -- albeit I miss having a source of reference open next to the editor at times.
