So far, EVERYTHING runs on VISTA. I mean I've installed The Sims, along with the Makin' Magic expansion, Rise of Nations, Lord of the Rings Return of the King. All run flawlessly. My emulators all work, win99 (ti-994/a), FCE Ultra (NES), Gens32 (Genesis) ALL work great. Firefox, and Thunderbird both run perfectly, Open Office runs. The only thing I haven't tried yet is VB 6.0. I've heard don't even try.. But we will know this weekend.
