Just when the internet is snappy, they increase the size of websites 4x. I doubt we will see "retina" displays on PCs anytime soon. 22" 120hz monitors still cost 300+ dollars. I can't imagine how much a 260+ DPI 22" monitor would cost.

Doing a back of the envelope calculation, a 22" 260 DPI monitor would have a resolution of ~4986x2804 in 16:9. Say goodbye to gaming.
