Vista ultimate or premium? I have xp pro on one of my machines and want to change to vista but I want to know if premium is worth it or should I go with ultimate? I have ultimate on my main machine and love it. My only reason is that I have a vista home premium disc that I have and it is fully legal but was wondering what the main difference would be. I seem to find it is very similar except for remote desktop which I think is important because I am networked. What would you do?
