Yes, we discussed this before, and agreed that spending time and money on a Vista/Win2k8 infrastructure wouldn't make sense for you since it doesn't bring anything drasticly new to the table.
But I think we can agree that Vista is as good an OS as XP was, and improved in many areas, and that the vast majority of Vista hating is mostly baseless hyperbole that people heard from a friend of a friend of a friend, without ever actually using it for any extended period of time, or often without ever having used it at all.
