Not that we’re biased towards covering this sort of thing, but User Centric has just finished a text messaging test which had iPhone, BlackBerry and Samsung E300 users send multiple messages from their devices. BlackBerry users had the best error rate, sitting at an average 2.1 errors per message followed closely by the number pad texter at 2.4 errors per message. The iPhone, however, suffered a wooping 5.6 errors per message. Youch. Expertise was a non-issue, as the error rate remained steady across all levels of iPhone experience. Speed between iPhone and BlackBerry typing was about on par, but that doesn’t do much to soothe the sting on the virtual keypad faithful.
