Maybe the longer Apple times could be for those Guided Tours and Tutorials ?
Yes, and perhaps some just watched those QT movie trailers. I wonder if visits to the iTunes store count as a 'hit' on the Apple website?
That is an extremely important question... if so, it would probably translate to the Apple site getting far fewer hits for computers than Dell or HP... i.e. that would likely be bad news.
I figure that's part of it, and like Mike mentioned the movie trailers, but it just shows that Apple knows how to draw a crowd and keep them around, like their stores.
