Coming over from android one of the top issues (and time waster) was the complete lack of tech support from my carrier VZ. you might as well ask them in Chinese what your windows issue/problem is; same applies to walking into any VZ store. say word windows they just stare at you for a moment then try to pitch you an android or iPhone. This a bid deal for people like me who migrated from android. Don't care how user friendly platform is like anything else there is a learning curve and former VZ android/IOS users are used to very thorough and problem solving approach for issues with VZ android/IOS devices from VZ ; support which simply does not exist for Windows platform now.
