at first i had lots of problems with vista, it took a month or so to settle down, if you leave all the 'bells and whistles' on then it will run slow - eg: when i had NOTHING loaded except standard vista programs that load on start up it was using 1GIG of memory...

anyway over time i have deleted or uninstalled or turned off all the crap and its not too bad now.

dont worry too much about vista - wait until you try the latest ms office applications, now they are really really crap!
