I bought a 12" Macbook last year because my 15" is too heavy to lug around. It's so light that I forget that it's there. I spent months on the road with it. At home I would just plug it into my USB-C monitor and use a keyboard and Magic Trackpad.

Unfortunately it's too slow to play YouTube Music in the background, especially if Docker is also running.

I would buy an M2 version in a heartbeat if Apple made them. I recently bit the bullet and got an M2 Air. It's a lovely machine that's better in every respect, but it's 30% heavier, and I can feel that every time I take it with me.

A 900 gram laptop that charges with a phone charger is just incredible to have.
