Gartner's not saying anything new or novel; they're just echoing Symantec's FUD, which has been thoroughly discussed here and elsewhere. Gartner's Analysis claims that Spyware, although virtually unseen on the Mac, could be seen in the future. Well, most anything could happen in the future, so that guidance really is not very substantive. I don't think this advisory is much of a problem - it's not like Windowze Enterprise weenies will ever care about the Mac.
