There is more to good (and great) experiences than usability. I don't agree with everything in this article on "What makes products great" but I did find this very amusing:
"Every time I read Jakob Nielsen," I wrote in 2000, "I get this feeling that he really doesn't appreciate that usability is not the most important thing on earth. Sure, usability is important (I wrote a whole book about it). But it is simply not everyone's number one priority, nor should it be. You get the feeling that if Mr. Nielsen designed a singles bar, it would be well lit, clean, with giant menus printed in Arial 14 point, and you'd never have to wait to get a drink. But nobody would go there; they would all be at Coyote Ugly Saloon pouring beer on each other."There is more to great experiences than usability, but do not overlook the value in making it easy for people to do what they want to do.
