A design study compares the on-screen keyboard of the iPhone with QWERTY and Bell keypads. People with no iPhone experience were asked to use both their own hardkey-based phone and the iPhone, and the results were then compared.
“Participants made an average of 11 errors per message on the iPhone compared to an average of 3 errors per text message on their own phone. Although the error rate was alleviated somewhat by the iPhone’s self-correction feature, participants were still frustrated.”
