I have Vista Business 32 bit, but I also have 12GB ram. Because of this I am going to buy 64 bit. home premium is $99, and Ultimate is $179.99. Is it with that extra $80 for Ultimate? Will I even notice a difference? I've read about the differences, and it is clear Ultimate has more features, but it didn't look like there were anything someone would even notice? None of the reviews actually consider the price component of it. Has anyone found Vista ultimate worth the price difference?
