No surprises here. Just like the lockdown on iPhone screen and part replacements, Macbooks suffer from the same Apple’s anti-repair and anti-consumer bullshit. Battery glued, ssd soldered in and can’t even swap parts with other official parts. 6000$ laptop and you don’t even own it.
There are two sides to that depending how bothered you are about updates.
Yes they support them with updates for, actually 5 years typically before considering them “vintage”, so they’re better that way. However you’ll find after about 2-3 years as the updates roll in, your iPhone mysteriously slows down. This is the planned obsolescence I’m talking about. They also did it with the Intel Macs - my 2017 one mysteriously slowed to a crawl (meanwhile Windows runs like a dream on it) the moment the first M1 supporting update came out. Very convenient.
If your view on whether a device is usable is based on whether it’s getting software updates then sure.
On a more practical level, people keep their Android phones going for 6+ years but without them being crippled. The software stops being updated after 2-3 years but this also means they stay usable and don’t get bogged down.
This “iPhones start slowing down” myth is just that - a myth.
No it’s not, I’ve owned several.
So have I. In fact I’m typing this from one that’s coming up on 2 years old while my wife’s is coming up on 4. Both still run like the day they were bought.
