I also agree that the Apple's "Switch" ad campaign is mostly targeted to mainstream Windows users and as such it should be plain and simple.
We shouldn't also forget the fact that the specific ad, according to Jobs, has been very succesful so far.
However, the fact that it was and continues to be succesful, does not make it a smart one. On the contrary, I find it a bit idiotic, but then again that is my opinion.
