Shaking Things Up.

A commenter on yesterday's post pointed me to what I take to be a computing professor's take on Gourville's work here.

His citing of the phrase "comfort app" was particularly intriguing. Initially, I thought how well it captures the idea that a successful innovation must make users feel comfortable with it, but then it occurred that a corollary (which brings in issues of taste and fashion) is that it must also make current users feel uncomfortable about not switching.
