Interview with Nat Friedman.
>The No. 1 misconception is that usability is a major barrier to adoption and that’s not true. It used to be. There was a study done recently with a group of 20 users who had never used a computer before. Ten were put at a Windows PC, 10 at a Linux PC and they were given a list of simple tasks like sending an e-mail, surfing to a Web page and the usability results were pretty much the same.
