The promo is a Flash presentation for Windows XP, and you can see it directly on Microsoftis Web site. In that promo is a PowerMac 8500, as well as a Titanium PowerBook. Perhaps Microsoft has ported Windows XP to Mac hardware after all? Please note that thatis a joke.
You can watch the entire presentation yourself, but we also took the liberty of snapping some screen shots for "posterityis sake."
