The point is more, no Nokia have not spend 4 billion dollars on R&D developing Meego last year.
The article, being engadget, utterly misses the fact that nokia do more than develop Symbian and Meego - I'd imagine the amount of money they throw at those two is a tiny drop in that ocean of 4 billion, compared to the amount they spend on both handset hardware, and infrastructure development. As mentioned countless times by the less blithering of Engadget's posters, have a guess where the majority of the development of LTE/4G came from, along with counless other "routine" infrastructure developments.
