My wife uses the moto G Play. <150USD for a perfectly functional phone, and frankly I'd even call it "far from minimal," (it has features that many flagships unfortunately don't support any more, e.g. sd cards, removable batteries, and headphone jacks) and for years have looked for an even more commodity platform myself since I have no need for apps or beefy hardware. (GPS, text, html only browser, email, with barely enough horsepower to run the above + a beefy battery would be the pipedream, and sounds _not too far_ from the brick phones I used ~20 years back)
As I told a coworker when I saw this post: Either our expectations of "minimal" or the english language has gotten entirely out of wack, because 350 pounds for a smartphone is so far from minimal as to be laughable. Maybe a "minimal flagship" (and this is where I'm inclined to think the gap between your view on this and mine is, where you said 'if you find good specs cheaper'. Perhaps my view on "good" is a much lower bar, but I'm perfectly happy with my 60$, 5 year old Lumia, and find it to be _far more minimal_, while directly challenging your "break down sooner or later" assertion; I've had droid flagships that didn't last as long.)
