In emerging markets, smartphones are gaining ground based on crazily low pricing. Check out this Gadget piece about recent figures from South African retail giant Pep. In the second half of 2013, 1 percent of the pre-pay phones Pep sold were smartphones. That was up to 13 percent in the first half of this year, and soon it will be 30 percent. Much of this is down to the arrival of super-cheap, WhatsApp-centric Android(s goog) phones priced as low as R399 ($38). Now consider that Microsoft(s msft) just killed off Asha, the low-end Nokia line that’s been its big contender in markets such as this. Those cheap new Lumias had better be really cheap.
