We should not forget that social networks are the drivers of revolutions (to say the very least). Clearly, Nokia makes fine stand-alone NITs, like my N800. But all current devices fall short in a key social feature necessary to drive a (capital "R") revolution: mobile device interconnectivity. By that I mean enabling two or more arbitrary NITs to selectively connect without requiring intermediating servers, routers and so on.

Nokia and Apple products are quite designerly, but it is more than mere rumor that people are inclined to connect in the local, physical space (as opposed to the dated concept of Internet space). Nokia, polished designs are not sufficient. Make them connectable, networkable. Do that well and you will witness a true Revolution!
