I'd argue 20 years of mobile development has given us a more powerful Palm with a SIM card and apps including ICQ with encryption, Skype but viable on a handheld device, email with office apps on a small screen, networked games instead of single player, maps, destruction of privacy from use of spyware on apps reporting every swipe, view of contact one has. I'd argue most enabling changes exclusive to mobile have come from video, which was already a concept, location, which was already a concept, real-time status (which is mainly Twitter and Twitter-likes) and bandwidth. The 'killer feature' at the outset being syncing music and a web browser with sufficient adoption to make saying no to IE 6's vision of the web, and Flash, viable. But I'm keen to know what was barely imagined back in 2000. Is it shift to mobile devices for a consumption?
