Don't confuse Nokia handsets with Nokia. Nokia itself is alive and well and had about $25 billion in revenue last year. The handset business was spun off to Microsoft because Microsoft was willing to write a big check. Making money on handsets is pretty hard if you don't have either a walled garden store (Apple) or make the actual components like processors, memory, screens (Samsung). Otherwise margins are very thin relative to Nokia's actual network products aimed at carriers.
