Just by including one single feature. FM radio. For example FM radio is fairly new in India and it has taken off well. So if a prospective Lumia 520 customer goes to a mobile shop, he/she is more likely to purchase a handset that comes with one. FM radio has a lot advantages in the emerging world, you don't have to rely on the internet and radio is ubiquitous. Not everyone here can afford data plans and the 520 isn't really for the affluent. I know GDR2 is coming with FM radio update. My point is Microsoft could have at least released FM radio when 520 was launched. Seriously a wasted opportunity.
