I have seen so many articles on HN in front page about M1 over the past few weeks. Like a curious child I read all of them because somewhere in me I want to believe there exists a possibility of a giant leap for Desktop/Laptop. Having tried it myself, I should say this is going to be remembered just like the iPhone in 2007.
The original Air created the class of ultrabooks which made the bulky Windows laptops at the time obsolete for average users.
The new M1 Air has created a class of laptops with ultrabook bodies, but remains cool to the touch under load without sacrificing much in performance and having 16+ hours of battery life.
Like the original Air the new one has basically made every ~$1,000 Windows laptop obsolete. Even really nice ones like the Dell XPS 13 have worse battery life and performance while reaching CPU temperatures as high as 100 °C.
