I just got an M1 Macbook Air this week to replace my 2014 Macbook Pro. Performance is cool (lots has already been documented about that), but the battery life is on another level. Charged it on 4 days ago and after about 7 hours of use, it's still at 48% at the time of writing this post. Ditto to what you said about "a beautiful marriage of form and function".
This may be a normie response - but Apple Airpods Pro are one of the best products I've used. After years of using several bluetooth headsets that get finicky (with connections that is), having a set that just connects and works every single time is refreshing. They really changed my behavior - I went from not liking phone conversations at all (getting agitated after a few minutes)to comfortably having long phone calls. I would replace mine immediately if they were lost / broken.
