Baymard has a write-up on Quick Views and Product List Usability. The key takeaway: Quick Views, which have become a staple for online Product Lists, often hide poor design in the Product List themselves. Almost everything the Quick View brings could just as easily be implemented in the Product List itself.

Good food for thought.

Quick Views are often symptom treatments for poor product list designs. Indeed the test subjects were only appreciative of Quick Views on test sites that had a problematic list item design.
