A Microsoft Research demo from TechFest 2012 of a lab touch system that lets viewers feel the effect of different input latencies, down to about 1 ms. It shows how much more responsive dragging feels compared with typical 100 ms touch delay.

A vintage demo video of the BeOS operating system running on mid-90s hardware. It shows media playback and window manipulation staying smooth at the same time.
