It isn't just thin: they are quiet and fast with the best trackpads, reasonable keyboards that (except for the idiotic move when they released the touch bar and dropped the escape key) have a reasonable layout that doesn't change much, and all of the power states work correctly every single time.

I am the second most stubborn person I know in my friend group on this, and after only using a desktop for a couple years during the pandemic, I avoided having a mac laptop for the subsequent five years and it sucked. I finally caved after I realized the new M5 Macbook Air is actually likely to be faster for web browsing tasks and is somehow also (awkwardly?!) competitive at compiling code to the monster modern Xeon build I had just completed, and it doesn't even have a fan!

As far as I am concerned, it is over: Apple has won on everything except screen quality (I am sadly now addicted to OLED and I fundamentally disagree with the Apple position of not having a touch screen on a laptop, a stance that is only more emboldened now that I spend a lot of time with children).

It's not the thinness, it's the amazing battery life.
