I had used them in the past and even tried to take them into their third and fourth years, but they felt sluggish and had more and more app crashes as I fell behind the adoption curve. At their price point I'm absolutely expecting a 4+ year lifespan. I think Apple has a different vision though and is aiming a little more upmarket than where I am.
Latter stage CPUs in iOS devices hold up better than they tended to 5 years ago. I have an iPhone 8 in my house that gets used every day. Not a struggle.. I do remember when a 2 year old iPhone would feel crippingly slow around the time a new model was released. Not the experience these days.
That's because they don't have to. A lot of Apple customers don't even consider competing products. Apple could release a Macbook without a keyboard and there would still be a contingent of users willing to stick with it and explaining that you start to prefer it after a while. A lot of their decisions were good, or at least made sense in the long run (and were just introduced earlier than customers would have preferred,) but they're pretty much unaccountable at this point, I think.
The “trash can” Mac Pro would like a word...
“Recent”? Apple has been focused on privacy for quite awhile , they just didn’t make a big deal about it. Apple has had my personal information including my credit card on file for almost 29 years and I have never received marketing emails from 3rd parties nor has Apple suffered a hacker security breach.
