> The mouse is a hardware sprite and its movement stays responsive and smooth even under heavy load and even when the OS freezes
Modern macbooks do something really interesting when the OS freezes. If the OS OOMs or something like a kernel panic happens, the trackpad stops clicking! There's something in the trackpad hardware that polls the OS and locks the trackpad when the OS stops responding so that it can't be pressed down to click anymore. Almost makes the OS feel like a real physical thing when this happens.
