I am the one who made the comments about Ultimate being better. Reason being, his friend felt it was worth going from a legal licensed copy of Home Premium to Ultimate. Lots of people made this mistake. "Hey, you wanna free copy of Ultimate instead? Oh yes, that would be awesome".
I would NOT have paid for ultimate myself. I just got my copy of windows 7 ultimate for free by attending the New Efficiency launch seminar when Windows 7 was released. With my own money, I would have chosen professional.
