To be clear, I'm not saying that everyone should use 300 ppi displays, or that everyone would benefit. But you need to remember this goes both ways. Not everybody cares about battery life. Some people want 5 hours, and everything above that is superfluous. Some people basically never even unplug their laptops. Not everybody cares about the performance difference; as long as it renders browsers and office apps, it's fine. Others want 4k because it's a pixel doubled 1080p, and they like gaming at 1080p. Some people never even use the built-in monitor. There is no single, homogeneous sweet spot. I agree that there are other useful steps. OLED laptops are happening, though scaling slowly. 144hz, variable framerate laptops are happening, and are set to completely take over the gaming laptop segment. Touch screen happened. Power efficiency is improving, a recent step being IGZO. It's not like these other aspects are being ignored.
