Jeff Atwood makes a good case that there's a relationship between screen space and productivity, and he cites at least one study to back it up. I tend to agree, but I'd add that it's only one factor in the productivity formula. Other factors include
- time of day
I'd rather work in a quiet place free from distractions on a small screen than in a noisy place on a large one.
I'd rather work on a tiny screen in a noisy place on a hot, humid day with solid process and infrastructure than work on a big screen in a comfortable room with poor process and infrastructure.
