My mom could never figure out how to double-click a mouse without moving it a tad. When she uses a tablet, she's understands swiping, but she can't help but touch the screen when a "normal" user would point without touching. She's starting to get it but I think shopping on Amazon may forever be out of reach.

She's definitely not the average user, and while usability is important to a website, the average user ought to be more concerned about security and privacy.
