I know there's a sizable contingent of people who just think a bigger number is better, but realistically this is a device for passively consuming text and video content that is typically around 30 fps anyway. Why waste the battery power on faster refresh?
Does the page look and feel glued to your finger as you scroll?
Yes, for me issues with apps have mainly been in poorly optimized code causing lag, slow loading and the like. The 60hz/120hz thing has never really been a practical issue.
I'm sure a lot of people now would feel odd if you gave them a 60Hz phone after high refresh has become so common, even if they don't pay conscious attention to that kind of stuff
