I just love when people make such statements that they would pay more for a feature-less product, when in reality we all know that's B to the S.
Noup, for me its paying more for an extra feature, the feature of more battery life, less heat, less network scanning/band hoping, etc...
I would go as far as saying the space took by a larger, less efficient, first generation 5G chip made Apple sacrifice other improvements, but, even if it was just battery, to my view this was a loss, its better to have the best, most efficient version of proven technology than the first generation of the bleeding edge one.
More so, when people talk about future proofing, I, like most people here, switch phones within 2-3 years, I havent heard a single use case, not one, that isnt possible already with LTE+, which gives you around 150 Mbps already. 4K live streaming, snappy downloads, etc. Is all something I can already do.
In my country 5G is MIA, and I dont think in 3 years time LTE will be shut off, so, I dont buy the future proofing argument about 5G.
