I’m still doing great even with an M2!
Sure it's nice the shiny new thing but has capitalism infiltrated people's mind that much? All my previous laptops died on me several times and became frankestein's monsters before I let them rest for a final time (to be often repurposed to other family/friends' machines).
Most M1 systems I saw use on-board BGA110 NAND flash, and thus maintenance/upgrades on the SSD are difficult. Most users don't have a hot air rework station or x-ray inspection machines to do this modification correctly.
The MTBF statistics can move around a lot depending on the use-case, but eventually people will run out of luck ( https://en.wikipedia.org/wiki/Mean_time_between_failures .)
Not sure why people get upset by this fact, as not all Apple hardware models were built to be disposable. =3
Good excuse to upgrade though, as a $1500 recovery bill would not be cool. Best regards =3
The corrosion inhibitors in petrol engine oil get fully depleted within about a year with most brands. One may certainly sell the machine before you see acidified lubricant related problems, but the motor will not reach its full operational lifespan ( https://en.wikipedia.org/wiki/Bathtub_curve .)
I do agree that anyone with a CVT style transmission likely won't have to worry, as that entire section will probably need replaced before you see significant hydrodynamic bearing damage.
"Buy cheap, buy twice" as they say...
ymmv, best of luck. =3
