So, on the topic of sturdy.... I have the Macbook Air M1, bought it pretty much directly after it came out, and it is sturdy as shit.
Just to iterate on the kind of abuse mine has already endured - without even the slightest dent or crack:
1) I put the Macbook on a chair and, without thinking, put a blanket over it while cleaning, causing my girlfriend to sit on it with her full weight for over 2 hours
2) I have dropped the laptop two times while carrying it
3) The laptop has fallen off my desk also two times because of the lack of Magsafe
4) The laptop was, in its silicone case, in the passenger seat in a 25-30mph car crash, got shot full force against the middle console
Not a single dent. Just some scratches on one edge from the car crash.
