I know this because my mom bought one a couple years ago and was able to set up her email and start emailing me photos from the camera before I even knew she had it. This is someone who can't set up her desktop email client without calling me for help.
Is it entirely certain that designing the operating system among sharing photos and posting status message updates will be optimal across all mobile functions? Not sure that it's the case.
That said, if they can penetrate the high school crowd, this might be a success. I don't think his mom is really the target market, but I could be wrong.
