    It runs low power CPU instructions, saving energy and helping the CPU run cooler.

    I thought it was the computer equivilant of fidgeting, i.e. if it had nothing to do it would try to shut itself down...its just giving itself the illusion of having a job to do...

    A trip down memory lane, when Win9x users could run software cooling apps like Rain or Waterfall... Link.
    Win2K, XP, etc just run HLT commands from the system idle process. Doesn't work as well as those utilities did, but it's good enough.

    exactly the opposite.

    not doing anything, and doing nothing, are two very different things.

    the system idle process tells the processor to do nothing - it rests, uses less electricity, generates less heat.

    the alternative is it just sits there not doing anything, at full pelt

    the higher the number is the less work you are doing well, thats what the management would say.

    when emulating windows in virtualpc, you need to install the virtualpc additions software in the client os - virtualpc can't correctly emulate the regular do-nothing commands, so part of what the additions package does is replace the client windows's sleep command with one which maps properly to the host os

    otherwise, an idle guest os uses 100% cpu power on the host
