None of the Macs I've owned had been durable, they've all had some incredibly expensive issue after the warranty expired that was not worth fixing
It's literally been the same thing with me and equally expensive Windows business laptops. HP is the worst offender, but for example I have a perfectly working Latitude 7 series (high-end business ultrabooks) where the carbon housing cracked over night after 4 years, out of nowhere just sitting on a desk. I have had a dozen similar issues (coil whine for example) that I've not experienced with Macs even once in over a decade.
So there will always be someone who says brand x is the worst, I am switching to brand y, whilst simultaneously other people do the reverse switch for the same reason.
Inflation means Macs pretty much double in price every few years
That is flat out wrong. For example: 15" MBP 2015 launch price: $1999. Today this sum would be $2,581.74 when adjusting for inflation. 16" MBP 2023 (M2) launch price: $2499.
The 15" MBP 2016 launch price was $2399, today that would be $3,038.42. So the 2023 16" MBP is actually much (!) cheaper than some Intel predecessors.
There isn't a single Mac that "doubled in price every few years" ever, at worst they didn't become cheaper, and in many cases they actually did as I showed above.
The difficulty of repairing these things puts me off paying a lot for them.
Even though that is correct, you can now keep the AC+ warranty for the entirety of the Mac's lifetime, beyond the usual 3 years. My Mac will last me at least 5 years and I will keep the warranty for those 5 years as well. For the $4500 I paid for it the AC+ on top doesn't make a big difference in pricing. And let's not forget the 14" was available through deals starting at $1599 brand new, so it's not like there are only very expensive Macs.
