I'm not trying to come off as elitist, I'm being a realist. I've worked at jobs where I sold cell phones, I've worked at jobs where I've supported cell phones. I've also worked at jobs where I sell or serviced computers. I've designed software. I've done a variety of these things. It's not saying that power users are elitist or anything like that, hell I'm not even sure where you came up with the me being elitist thing at all. I'm saying that most users don't care enough about literally anything to figure out how things work, they just want them to work for them. I've seen this attitude with just about any piece of hardware, software, and operating system you could ever find. This happens everywhere between more power users to the absolute basic users who almost don't know how to turn a device on. People don't want a phone to just have the option to do task A, B, and C for them, they want it to do it for them without asking.
And to say that not reading every single instructional message or knowing how every feature works means it's the users fault if anything goes wrong, that's just kind of crazy. Yes, Windows 10 comes with a decent amount of instruction with it, but not on every single button and every single layer.
You know why people love Mac and iPhones so much? Because it just works. You don't have to learn a million different things, the device just works and is incredibly intuitive. People don't love Apple products because you can do a ridiculous amount of stuff with them, they have better hardware, better software, etc. It's because the products simply work.
Moreover, to expect someone to know every single in and out, every quick, every feature, and every function of every phone they buy is honestly asinine. A phone is supposed to be a phone. Most people probably won't touch half of the true features of the device. On top of that, it's just a piece of technology, there are in general more important things in life than knowing everything there is to know about your phone.
To me, that's why I enjoy Windows Mobile. It's always done the things I want it to do, and it does them well. It reads out text over the Bluetooth in my car. Live tiles make it easier for me to preview data and news without having to browse through an app, it integrates with Exchange, Office, and OneDrive really well, and it takes really great pictures. I don't need to know every quirk of Windows Hello, I don't need to manage all of the permissions of every app, I don't every single feature that's on the phone, but it's nice to know they are there. And until I need that feature, I don't need to know anything about what it does.
