245 ppi is nowhere near what the human eye can perceive. You can make all kinds of assumptions about view distance and so on, but higher resolution is almost always a better thing when rendering text, rich content, and so on. You kind of sound like the people of the past who said "we'll never need a terabyte of storage" or "256 MB of RAM is enough for anyone" and so on.

Just because you can't perceive individual pixels doesn't mean you can't perceive higher quality. Imagine if you wanted to draw a human hair to scale, you would need some small pixels to make that look good.

However in most smartphone use cases, that's probably not an issue.

There is definitely a need for high ppi screens as new VR devices like the Oculus Rift come out.

Oculus Rift style VR devices need screens with even higher density. I'm glad the show is continuing.

Well 1080p is nice in that it is quite widespread standard and as such eg display cloning from your phone to a desktop monitor/tv/projector should be trivial. Also you can play media content without needing to downscale (albeit this is fairly minor advantage).

What the human eye can perceive is dependent on the distance between the eye and the screen. Perhaps some people like to hold the screen very close.

Indeed - I'd rather have more battery life.

It has come really far when my new phone has a higher pixel ratio than my two-year-old 15 inch laptop
