Sorry, I started skimming after a while. Sounds impressive and I'm sure someone could probably build one.
But....how much! I know its a flagship, but each of those things come with a price tag.
You are right, but it is a flagship, if people want a flagship they spend money, otherwise they get a midend device. Plus in america we still have subsidized contracts so people are willing to invest in a 800$ phone if they are only paying 200-300$ for it.
