But people do. The point here is LATENCY, when a user comes back from lunch and continues typing in OpenOffice, his system should behave just like he left it. Making the user have very bad interactivity for the first minute or so is a Bad Thing, even if the computer did run more efficiently while the user wasn't around to notice... IMHO, the VM on a desktop system really should be optimised to have the best interactive behaviour, meaning decent latency when switching applications. -- "Debugging is twice as hard as writing the code in the first place.
