You are missing the point. Vista will load up your apps in RAM just like XP
and any other OS. Vista will also start filling up the ret of the RAM with
stuff it thinks you might need soon. If another app comes along and wants
more memory then some of this will be freed to allow the app to run.
In effect you still have all you spare RAM, it is just being used like a
cache, but will be freed up instantly if anything needs it. Trust me, it is
a little strange to get used to at first, us Windows users are used to
trying to keep RAM free, but Vista really does not work like that.
Can't think of a sig at the moment.
Read this instead.
