I don’t know if they’ve increased the price so much that people are no longer buying it or that they made the M1 models so good that people don’t need to upgrade.
I have an M1 Mac Mini and I really don’t see myself needing to upgrade for at least another 3 years.
I’ve already had it for one and half years. But yeah, still fairly standard.
Which is why Apple should have followed a 2 year refresh cycle for Macs. But they started moving to M3 within a year of launching M2.
