Actually, time has changed the presentation of the thinking . Back in 2011 it was a case of 'we're not going to be able to be as successful with Android as other users of the OS', now Elop can point to Samsung and say 'that's what we expected'.
With the same accelerated schedule, a mythical Nokia/Android device would not have been available until Christmas 2011 in limited numbers (which is when the Lumia 800 launched). Given the Samsung Galaxy S2 arrived in May 2011 to start the annual Galaxy S jamboree.
I still think a Nokia Android handset would have given the Finnish company comparable results to Sony with their Xperia range - two iterations of handsets to work out the platform and then some well-received hardware in the Xperia Z and Xperia SP. Sony have shipped 3.2 million handsets in Europe for Q1 of 2013, compared to 6.1 million for Nokia, but the Japanese company has still to get its flagship handsets on sale in the US.
