I don't mind spending a thousand bucks every 7 years to upgrade my laptop. I've had this macbook air since 2020 and besides the speakers don't being the best... I have no complaints.
I don't really see a world where this machine doesn't last me a few more years. If there's anything i'd service would be the battery, but eh. It lasts more than a few hours and I don't go out much.
Even the "few thousand" for a bit of extra RAM and SSD are highway robbery.
Anyways to each their own, I also had things break and repairability isn't really a thing with Apple hardware (while it easily could be if they wanted - even if difficult and by certified technicians instead of myself)
