Yeah, I have a VIsta machine at hom etoo but I never try using it for any music production. It will run just like XP... in about another 2 or 3 years after a shedload of service packs and fixes have been released. If I was starting from scratch again I would go the Mac route but I'm so entrenched in Windows OS that I don't think I could ever get used to the transition.
Light, re your own OS, a full terrabyte of drive space is major! :eek: I thought my system was good at 500GB :( What kind of ram have you got in that monster??
