Insult your competitor's customers. That will get them to switch!
Well, it did work for Apple pretty well with the Apple vs. PC campaign =)
Kudos to Samsung for creating a somewhat cool commercial. However, they'll learn that you can't sell an un-needed product. That phone is just too big. I like how back in the 80's we had those big phones (Zack Morris style). Then we went to tiny phones (nokia candy bar phones, RAZRs). Now it's like Samsung thinks we need to go back bigger - no thanks.
What a waste of marketing efforts on a product. But from a branding point, I think Samsung is making good headway on their perception versus Apple.
