I'm not sure the (productivity/inch of screen) metric is something we want to optimize. If you reduce your screen size by 50% (24" to 12") and only lose 40% of your productivity, it's not really a win to me. Granted I use 2x24" monitors in portrait orientation and still maximize everything, so I may be an outlier here. The side effects of screen size reduction are really what provides a benefit for creative work: control your work environment, ruthlessly cull distractions, minimize useless meetings and interactions. It's a classic recipe for achieving flow, and you don't have to reduce your screen real estate if you don't want to.
