The best technologies to keep your head up in everyday life are voice activation, perhaps an Air UI that works well, and something akin to Nokia City Lens, which could be piped through designer glasses, like the Facebook spy glasses I've heard a little about, to show you around your city. The vibrating tattoos are interesting, since the purpose of the vibrating was lost on the soul who made the N9 vibrate so weakly. I would have emotional facial tracking, so the phone can tell you when your date is losing patience with you. Autistim = solved.
