I have two MacBook 12”, one produced in April 2015 (one of the first) and the other in July 2019 (one of the last), needless to say, they are my favorite Macs, despite all their flaws.
I used a last edition 12” PowerBook from 2005 to 2015, and the only real replacement was the MacBook 12”.
The reason for so much appreciation? It's an iPad, in fact it's better than an iPad, in terms of weight and size, but it's a Mac. An iPad will always remain only an iPad (and I love iPads, especially minis), it's great for those who need an iPad, but I'm not that young anymore and I'm better off doing some tasks with MacOS.
