There is literally no value argument for having an expensive phone anymore; $150 will get you a phone that would have been considered flagship 3 years ago, and there are few, if any apps that genuinely need the CPU and GPU power of anything over $150 these days.
Indeed. I picked up an LG G4 earlier this year, and it does everything I need and then some. Granted it's more than $150... but aside from unforeseen mishaps that result in its destruction, or lack of carrier support, I see no reason why I couldn't still be using this phone 4-5 years from now. It's even got a user-replaceable battery, so it doesn't have that all-too-common path to planned obsolescence.
I looked at the G5, and there was no compelling reason to get that over the G4. So I guess just like my PCs, I've settled into a mode of buying last year's tech, because it offers better bang-for-the-buck.
The iPhone7 has no USP.
Frikkin' TLAs. Had to look that one up. I initially thought the 'P' stood for "port", and was all like, "WTF?!?? They left something else off in addition to the headphone port?"
