Yeah I have 3. I can & do use just one when I work from home on a laptop, and I've long been a fan of "uni-tasking" so I totally see his point. But it tends to be not-as-fast. My usual modus operandi with 3 screens is to have one instance of the IDE in the middle for whatever I'm working on, one instance on the right for the relevant dependency or example I'm following, and then on the left is usually some type of docs or Stack Overflow. Or Hacker News if it's break-time. When my neck starts to hurt from looking left for too long, that means it's time to get back to work!
