Neither of those 3 companies main adversting campaign is to directly attack their competitors to the degree Apple has. If your product is so great tell me about it. Its a slimy way to do business. Pepsi has done it in the past but nobody takes the cake like Apple.

BTW I don't drink Pepsi either. ;\)

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
