Submission + - Current Windows Phone Devices Not Upgradable (winsupersite.com)

Customers who purchase the current Microsoft/Nokia flagship phone will never receive a single update to the next version of the OS. In contrast, this is something that would never happen to a customer who purchased a flagship Nexus or iPhone where one (or more) updates are a given.
