Small correction: I think budget phones will feel it the most. The budget market has been practically wiped out at this point.
That was still after the RAMpocolypse had started but hadn’t hit Apple yet, I remember thinking Apple was immune
The M4 Mac mini was announced two years ago with 16GB RAM standard, starting at MSRP of $599, without anything like an education discount (which knocked another $100 off the machine), and stayed at that price until early this year when supply simply evaporated. Then the M6 model this fall went up by $300 for the same base memory and storage capacities. +50% in overall price of the entry-level machine, and probably not much of it was due to the M6 being a more advanced processor than M4.
