I agree, but I think it's more this specific implementation than the concept itself. I've seen plenty of "long-scroll" (not sure what to call it) style sites that have been absolutely amazing at dumping information into my head.

For example, http://www.apple.com/iphone-5c/

Bad example imo. A good one would have been http://www.apple.com/iphone-5c/features/ which doesn't break scrolling AND gives hard facts.

Agreed - worst thing you can do on a long scrolling page is hijack the ability to scroll like that!
