Purchased a new computer in April, an off the shelf Gateway model that has quad core, 8 GB of memory and runs Vista Home Premium 64 bit. I should not have any problems running Win 7 when I decide to upgrade. 
Oh and I still have my P4, 2 GB, XP Home 32 bit system that was revived from near death.

Probably should have had a response option for folks like myself and the others who have all ready purchased a computer this year, just a thought.
