Multi-functional devices have been around as long as, well, as long as devices. Some clever bunny tries to cram two, three or more devices in one form but so far I don’t think anyone of them have worked. And to illustrate the point MobHappy is covering the fact that four out of five mobile users use their phones for, wait for it, phone calls! Shock, horror!! Outside of press releases, I’ve yet to see/meet one person on the street who claims a burning desire for music/video/email on their mobile phone. Socially, technically and financially, we’re nowhere near the need for an all-singing and dancing mobile phone, so let it lie.
