I think that was completely unnecessary... Sure, sex sells, but it's cheap and desperate, and will probably turn off most female users. My advertising degree taught me only to use sex when it was really relevant or clever... Not blatant and in your face. Then again, it just goes to show the internet is for the most part a giant porn magazine...
I suppose they're not so worried about the younger people who use the internet either.
That being said, it was a hot ad.

I just think it could've been classier and a bit more appropriate.
