I switched from a 2014 MacBook pro to a 2020 M1 MacBook Air, yeah the CPU is much faster, but the build quality and software is a huge step backwards. The trackpad is feels fake, not nearly as responsive, keyboard also feel not as solid. But now I'm already used to it.
They also feel very bulky/innelegant while still being fragile for the most part and not really hitting workstation level territory.
I don't understand how people are enamored with those things, sure it's better in some way than what it was before but it's also very compromised for the price.
