The responsiveness point somehow resonates with me; I recall running 3D renders in the background (taking up 100% of the CPU), while running simple games in the foreground set to "high priority". The games typically never stuttered. Yet my android tablet routinely freezes for 30 seconds for whatever reason. And yes, app crashes could take the machine down, but it was typically back up in a usable desktop within 6 seconds. And later on (mid 90s), they seem to have become far more rare.
