I've seen a few examples of performant SPAs providing a better user experience, but I can only think of a couple. One example would be the Timbuk2 bag customizer: http://www.timbuk2.com/customizer#/product/15-custom-commute-laptop-messenger-bag/size/4/customize http://www.timbuk2.com/customizer#/product/15-custom-commute... But even this seems possible without committing to an SPA architecture. If I recall correctly they are using Ember for this. But yeah, you're right.
