OP here, thanks for the comment. True, I should have elaborated a bit more. Actually my 10 years old MacBook is still running as my wife's computer and the 15 years computer, I gave to a friend, which used it for a long time (not sure if still).

My comparison was with Windows PCs, that always were super slowish after 2-3 years. The built quality always felt cheap. The battery was done after 2 years. Maybe it was also an unfair comparison, that I bought cheaper PCs, but at work I recently had to a dev HP laptop much later, and I had a very similar experience.

So maybe the problem is more windows than the PCs, but if you have used MacBooks, then you definitely know the difference. Running a Lenovo now, I love the much other things. Let's see how long it holds. ThinkPads are defenitely in a similar categories as Macbooks, kind of unbreakable. Love them too.
