Maybe platform was burning, but all Nokia had to do is pick a water, instead they added more fuel into fire.
They had Maemo/Meego - should've picked Android port QT there and keep developing their own Linux based OS.

Also telling customers Symbian is obsolete was a disaster move - basically means forget about updates, guys. Who would buy it now? Same for N9. I guess half of the people who was interested, changed their mind after that, just like me. So is developers.
