The iPod Dance Commercials

So a friend of mine and I were talking about Apple and their products and the subject of the iPod adverts came up with the anonymous dancers silhouetted in all black with the iPod being all white.

Click here for one of them.

I remember hearing the musicality of the commercials, and I remember the good dancers and it made me wonder: Do you believe the dancing and music were effective in selling the product? I mean iPods were pretty popular on their own, but do you think these commercials contributed to their popularity directly? And what about dancing in commercials and adverts in general, do you think it's effective?
