Actually I run windows because I'm a lazy bastard and it requires the least amount of effort.
there are few types that require least amount of effort. one is as you said, lazy bastard who are ignorant of the technology yet have nothing else productive to do. the other type is the people who are really busy with something else that they have no time bother with the auxiliary/additional parts/devices they want it work first time because they are too occupied with other more productive task. these people will make this as a point to choose premium like iphone etc, but i find it similar to android, if we even have to register this and that and tuck in to that or this cloud etc in ios. other than that, they just work first time (android) so i dont really see a point choosing more expensive device even among android models.
Large part of Apple's problem is probably that the technology is maturing.
not just apple, it happened to other corporations in the business line as well. and no, technology is not maturing yet. it matures when we can communicate or play games with just from mind. 3d hologram, tele kinetic, 3d hand gesture like in minority report, true voice to text (any language) program etc, there are many innovations can be think of, but we are not given the "priviledge" yet. it will be "given" one bit at a time, when it comes, you'll see the cycle will happening again among corporations, with just slightly different face (feature), but the trait remains the same. i guess major corporations attended some sort of symposium somewhere, when there is new technology, you'll see everybody will do the same, start running again on the same whistle blow.
otoh talking about largest screen, i missed real buttons keyboard on the phone, with this argument... regardless android or iphone, all of them sucks, why there is no real AI that can distinguish our intention is it real touch or screen swipe, or just accidental touch in which the phone will not do anything?
with real buttons, i can type while driving without taking my eyes off from the road.
