Lumia 920 most popular among WP devices
When news broke out that WP was outshipping iPhone in several markets, critics were quick to point out that this is mainly because of sales of cheap handsets and iPhones don't sell in these markets because it is too pricey. The insinuation was that only cheaper handsets of WP sell well as it doesnt compete with iPhone on price.
Here's data which shows that the top selling WP globally has been 920. So much so that it has the highest market share among WP devices. So this should put to rest that WP/Lumia are successful only at the low end.
