But not this one. Whether due to the fact that it's fan-made, or some other reason, this is one of the most violent "advertisements" we've seen. Basically, it all starts with the innocent, white iPad playing its favorite piano melody, when, all of a sudden, it's joined by the Microsoft Surface, and that's when the music changes from sweet piano to dubstep - you know, the one from the Surface ad. What happens then? Oh, we wouldn't want to spoil the surprise for you, but we guarantee that it's quite unexpected, and even a bit gory.
