Maybe? This is something people have been doing for awhile now. I seem to know two camps here though: those who want the latest/greatest, then the slightly older generation who wouldn't give a rip about the newest technology/features (i.e. My mom).
I think the first group you mention is evolving due to a few factors... maturing out of the pop scene run by materialism and cool just by age... and the second factor being innovation. Why buy a phone that looks identical to the one I have with a tiny speed increase and a "pinch and pop" feature when I can do absolutely everything else just fine? I had every single revision of the iPhone up until the iPhone 6 plus. The battery is starting to annoy me second only to ATT's crap bandwidth limitations on my "unlimited plan" that I'll jump for an iPhone 7 Plus on T-Mobile.
