I have been reading up on Windows Vista and it is going to have 6 versions depending on your system requirements. Vista UltimateVista Home BasicVista Home PremiumVista BusinessVista EnterpriseVista StarterWhat is the price difference going to be on an OS with these variablities? Is it neccessary? I am just leary about upgrading to Vista if all it is, is Aero 3D effects. I am not into the sleek new interface, with streamlined start menus and eye popping graphics. I use an OS for functionality not for looks.I currently run XP pro and SUSE, but I will have to wait and see if there is any use for me to upgrade my XP in the near future.By the way when is the actual release date?
