Firt off, I think anyone or any article still ever so sure of feature phones dying completly off anytime soon just needs to be disregarded straight away. Pencil it in: Feature Phones will still be a large money maker a decade from now. Maybe it will be only 20%-30% of mobile sales, and yes I am sure Smart Phones will be outselling them, but there will be large markets for feature phones. Cheap always sells.
However, if the Asha series is still a part of that, I will fall over and pass out. MS has bigger fish to fry. They will trim down this purchase of all these Nokia factories and employees to something they are comfortable with, and they will want the emphasis on WP growth and features. Obviously, less then 48 hours from where this was announced is a stupid time to debate how this purchase will effect who and when. But, seeings how it is big news, there will be guesses galore. Mine is the Asha series exists for 2 more years and gets phased out.
