These outrageous pixel counts are murder on gaming. I'm glad my phone is 720p and I will not be buying anything greater than 720p until the SoC is 2nd gen 14nm or better. I've put my phone in the freezer a few times to cool it off. One time I left it in there for too long and it incurred too much condensation when I took it out. Not a good thing. But its fine to put in there for a couple minutes. It drains the battery a lot faster when its hot.
I see 1080P as the sweet spot for now.
Probably my eyes (mild astigmatism), but even up very close, I cannot tell a difference in resolution between the G2s 1080p display, and the QHD one in the G3 no matter how hard I tried. This includes aliasing in games (or lack theroff) as well as fine text and such.
Unless for whatever god forsaken reason I end up with bifocals (with my clarity degrading at less than half a foot at that), I doubt I'll benefit at all from higher resolutions at the same screen size. Now, what would be nice is if the display didn't always end up on top of the battery hog list, even at high brightness levels.
Edit: actually, I'd love to see some 120 hz displays too. I feel the refresh rate could provide a more "solid" impact than cranking up the res.
