Apple's success isn't built alone on technological innovation. It's also built on image. Part of that image is that the company knows what it's doing and its products do what they say they will do. "It just works" isn't a mindless mantra. It's a fact.

That competence translates into consumer trust. No matter how cool your technology is—and by most accounts, the Lumia 920 is very cool—if you present yourself to consumers as the gang who couldn't shoot straight, you're not going to make any headway in the smartphone market against Apple.
