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.
