I've never seen a more-true statement on this site. Years ago, my wife was using a $500 Acer laptop, which was a cheap plastic POS, which broke after a couple of years. I bit the bullet, and bought a pre-owned Air for $900. She is still using it, 11 years later. I used to have to fix something on her Windows computer every other week. Now I hardly ever have to help her with anything.
A year later, I bought another $900, used Air for my daughter. She is still using that, 10 years later. I bought a new MBP, and gave my son my 7-year-old version. I expect him to get many more years out of it.
People who have never owned a MacBook expect that they "wear out" like a $500 laptop, but they just don't. They cost much less over the long run. It's like hiking boots. You can buy cheap ones every year, or bite the bullet, and pay 3 times more, and have a pair that lasts for 10 years.
