I've always found ads that simply point out and amplify the "problems" of a competing product to be highly distasteful and somewhat childish. I think that, rather than focusing on your opponent, you should try to show the good qualities of your own product. We all know Vista has its issues, myself included, but I simply can't understand why Apple does not attempt to explain how its own OS is superior. It really makes me cringe when I watch ads like these, even if I'm a fan of the maker's product.
