Another observation on the iPhone launch. I find it fascinating that everything you want to know about how to use the iPhone is online and in video form. Conventional wisdom says that most people are visual learners, yet most product instructions are heavy on text, with a few simple graphics or screenshots added for good measure. Apple's use of short and long videos (called, brilliantly, Finger Tips) to explain features and common tasks is perfectly executed and brings visual help into the mainstream. Want to know how to activate your iPhone? Watch a video. Want to know how to unlock your phone? Watch a video. Remarkably simple, friendly and helpful.
