Hopefully in the next few years we'll see a 40" 4K OLED monitor at a reasonable price ($2000 or less). The Dell 30" OLED is a good start, but far too expensive. And the size is an issue for PC users. OSX can do DPI scaling very well, but Windows can't. Every time I've used scaling more than 125%, I get too many glitches and problems in various applications (and sometimes even in core Windows components). This is why I sold my P2715Q - I was running it at 200% scaling on Win7 and had far too much trouble. A 40" 4K monitor can run at 125% scaling and give a massive amount of screen real estate. I'll probably soon buy a Crossover 404K Final to hold me over until the OLED goodness is available.
