You can definitely take it to an extreme. If you only read one word at a time, why show multiple words on the display? Why not a single character! But that's not the point. There's an optimal level of visual busy-ness. Doubling your screen real-estate looks cool, but is it actually better? For me it is not. I had a friend at work who had a four-monitor setup, and then somebody quit and he got ANOTHER thunderbolt monitor. Once he had all 5 set up, he got so agitated by the quantity of data coming in that he couldn't get anything done. I would bet that everybody has that threshold. So how much stress was he feeling with 4 monitors? Probably some... maybe not more than his baseline daily work-stress, but did he need to take on that extra stress?
