Yeah, or mabye someone can write something like wine for windows....
So that programs for windows XP will work for Vista.
I must say though that this is rather suprising as microsoft have always made sure that older software is always compatible with it's new Os's
But Vista seems more like trash with a gold wrapping.
I seriously doubt it will be popular with people.
Anyways, if it won't work with vista, there's always linux
