Is there a valid reason for Retina or 4K computer displays?

All I can say is that when I switched from my regular screen iPod to a retina display iPhone it was very noticeable. The photos just seemed brighter and better than they looked on the iPod. Photos that I thought weren't even that great somehow just looked better on the retina display.

And my girlfriend can totally tell that her $100 bottles of Aveda shampoo are "way better".

Maybe you should check if you need (new) glasses. The difference between ipads/iphones before and after retina display is huge!

Maybe I'll go to the Mac store and have a look.

I use an HD projector throwing a 3.5 metre diagonal and I sit 4 meters away.

I love the big screen picture. It is so immersive. It is not the same sitting closer to a regular 50 inch screen. You need a genuinely big picture to get a truly cinematic feel from viewing.

Projectors only work at night time though.
