[Hawkee]

I've been developing from a single screen for 17 years and have never desired a second. Part of the reason is I work from a laptop and rarely at a desk. But practically speaking I get a lot of work done on a single screen. My eyes can only focus on a single window at a time, so I have no problem using swipe gestures to quickly jump between tasks. Another advantage is I don't need to twist my head every which way to view different windows. The window I need meets my eyes rather than the other way around. While the article is mainly an opinion and offers little scientific research I do agree with his opinion.
