I'm sure mouse latency is a big issue for iPad Mini users.

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?

The ProMotion screens have variable refresh rate depending on the content displayed. 10Hz to 120Hz for iPhones and 24Hz to 120Hz for iPads. So in theory the power consumption should be even better than a regular screen for static content like reading text.

I know you’re being sarcastic with that first line, but touch latency is even more noticeable than mouse latency.

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.

Yes? That was true even of the first iPad.

It’s definitely not true even now. Even a moderately fast finger drag will lag noticeably - usually by at least a frame in even very carefully tuned situations. It’s just physics. If you aren’t noticing it, you’re just used to it.

Try rapidly dragging up and down to scroll a web page.

For some people, it’s motion sickness inducing of it gets too laggy

Not sure about iPads, but going from a pixel 3 to a pixel 5 made me feel like my pixel 3 was broken. Xr to 16 pro was similar, but that is because Xr was legit broken.
