We like buffering of keystrokes or gestures when the system is completely reliable, exhibits reasonable latency and low jitter in its latency.

Even in unstable or high latency I like the buffering. I’m thinking of a remote shell, where you want to type a command blindly, and see it appear seconds later, because keys got buffered in the Internet pipes. Without buffering it would feel awful, having to wait a full roundtrip per keystroke
