When I was learning embedded design, the general rule of thumb was to aim for 10ms polling for user input, because human tolerance for delay is around 100ms so 10ms appears instantaneous. Then I see products like Nest come out, with big endcap displays at home improvement stores, and I'm like how do people not just immediately write this off as janky trash.
Then again maybe the extra lag (and jitter!) is gets a pass because its part of these products positioning themselves in the niche of "ask the controlling overlord if you may do something" rather than "dependable tool that is an extension of your own will".
