Meanwhile Samsung are slaughtering Apple in display quality.
I will assume this is an undisputed fact, for the sake of discussion.
However, iareSamsungs displays awesome and Apples is poor, or is Samsungs awesome, and Apple really really good, but a bit less then awesome?
If the latter, people generally do not know or care. They buy on price. Some buy on OS, some try to get the best combo of price, screen size, storage for their budget. Consumers are not like us on this forum
