They're very similar, but handling both together my old 2016 12" is just slightly smaller and lighter in a way that is really appealing compared to my 2020 13"

They're very similar, but handling both together my old 2016 12" is just slightly smaller and lighter in a way that is really appealing compared to my 2020 13" M1 Air. It's 350g lighter, which makes more of a difference than I would have guessed when throwing it in a bag.
