	tl;dr: Comparing rotate-image buttons on iPhone vs. Nothing Phone/Android, the author shows iOS buffers rapid taps while Android ignores taps during animations, forcing users to wait. This matters because even "casual" interfaces eventually get power-user treatment (e.g., rotating dozens of photos), and blocking input on animation is bad UX. The fix: buffer taps, or accelerate/interrupt the animation—never make users wait for it to finish.
	HN Discussion: ↑Broken button feedback and buffering issues are widespread across software •Apple's UX has regressed but competitors are still far worse ~Buffering can backfire, as seen in iPhone lockscreen or Jobs demo mishaps ↑Animations should be supportive, not blocking; waiting on them is cargo-culting ↓Blocking input during transitions is sometimes necessary to prevent mistaps
