How far away do you sit?
From my calculations the absolute maximum a person could use from 9 feet is 200DPI, but that is a little overkill (beyond the point of just smoothing jaggies) so even if we stick at 100DPI, half the absolute maximum that a I can see, a 4K screen should be no smaller than... 44 inches, at 9 feet, that's pretty small. Actually when I do jaggie tests on my laptop (100DPI) screen 9 feet is just where the jaggies start to blur. So for more average seating a 60 inch 4K display at 12 feet is about right.
If you want to avoid aliasing then really you should say that a 4K screen should be no larger than 60 inches at 12 feet. It's almost backward that everyone seems to want to be able to see each pixel on their screen, lowering image fidelity compared to their normal vision of the world around them.

Once these displays and devices become more common the average person will just love them, and given how close you hold a tablet or phone to your face, I have to agree with the Forbes article that the pixels per degree of 4K mobile devices won't be wasted at all, to the extent that we could probably use 8K tablets as well (10 inch 8K is 800DPI, which viewed at 1 foot is right on target).
I don't like the idea of 8K on a phone though, holding a device 6 inches away from your face just sounds like too much.

On another subject, my bet is that 8K and 4K will be the division between "premium" and "average" content moving forward for the next 50-100 years (until we find better display methods). 4K will be the standard that everyone uses but high end movies and such will shoot for 8K. Right now the Japanese are aiming to have 8K broadcasting ready for the 2020 Olympics.

No, not until mobile GPUs can handle it. Which will be LONG after desktop GPUs can.

2K screens are coming out this year....you better believe 4K will be here next year or 2015
since when did mobile GPU's rendering capabilities slowed down the adoption of higher and higher pixel count? I remember when 720p phones first launch they had terrible battery life...wait same thing applies to 1080p phones. The PowerVR from 2010 ran okay for my phone though at that res

I want everything to be 4K so we can have 4K content. 4K in PC will push GPU makers to the limit. The leap from 1080p to 1600p is much smaller then 2160p. Right now there are quite a few GPU can then play 90% of the games out there @ 1440p 60Hz.
4K will require ~ GPU 2 - 3 times faster then the current best.

Meh, my >3'' screen doesn't care about this. Huge phones are silly, so I'd only see the need for this on Tablets, but on those I wouldn't be watching HD content to care enough.

Oh, it'll happen, but it shouldn't.

I'd rather keep getting 1080p screens with increasingly better GPU's. At least this way the quality of mobile graphics in 3D games can be improved.

You will not get 4K games in mobile. Also quality games does not have to do anything with graphics in mobile.
