While having Vista up and ready here I stymied back to XP to get things done since the tv tuner card also used for video capturing only has XP not Vista ready software available. For games most here went on easy enough with one or two refusing to even install. But that's no surprise since upgrading from 98SE to XP or 95 to 98SE saw the exact same dilemna for the most part.
I still keep the Classic Windows theme on Vista and was not even impressed by XP's style let alone the new aero styling seen in Vista. Many rushed out to get Vista styles for XP and then saw problems getting rid of them afterwards!
