Whether users want to scroll or not, depends from situation to situation. Visitors will not always scroll. So it's not just a myth.

It depends on the type of page and the type of website.

A nice article illustrating when users want to scroll (and when not) can be found at http://webusability-blog.com/page-fold-fact-or-fiction/. It also gives some good examples of good use of the area above the page fold.
