There was a cool animated(if I recall correctly) video from probably 2010-2012 era; I believe before the N9 and N950 came out which showed a phone which looked like an N900 doing things like sharing location via chat and using NFC taps to pay or exchange contacts. It was a cool expo vid of a Linux based Nokia flagship in a timeline which never came after Elop/MSFT lit our platform on fire.
I know the link(if it is still up) is somewhere in the TMO archives but I have yet to find it after searching for a few weeks.
