On some of the forums I go to people already are saying they have no interest in seeing people's pores in detail, how much makeup they have on, etc. How much resolution do we need? Also, as one guy put it, I don't have 4K eyes so what good is it?

Well if a small display had a higher resolution it could be optically magnified to show greater detail. Perhaps it would use less power for a given resolution display or be easier to package.

It should be like looking out a window. Its no ways near that yet. It not detail so much as accuracy.

I agree with mitchbaskett. The only advantage I see is something like displays on the side of blimps. They would be viewable from miles away. But my TV is already amazingly clear.
