the Lumia 520 is probably the most popular and most used windows phone currently out, but Microsoft needs better hardware for WP and one wonders shouldn't they make a nexus type device like Google does with android .Nexus devices are very popular because they have great specs and are priced aggressively wouldn't it be better if maybe they sold this nexus type WP instead of multiple entry level phone(520.530,635).I know Google does not make much of a profit on the Nexus phones but the phones sell like hotcakes and gives Google more market share and as a plus they have consumers with phones powerful enough to run all apps smoothly and more importantly Google services
