It's when we saw the 12" Macbook as the crusade for thinness at all costs (terrible performance, only one port, a terrible version of the macbook Air), the end of the Macbook Air (before getting resurrected a few years later), the butterfly keyboard (allegedly to save 0.5mm in thickness), the Touch Bar (primarily there to boost Average Selling Price) and the loss of MagSafe.
I was surprised last year how good the M1 was. The second generation looks even better. This thing has function keys back, no Touch Bar, MagSafe!!!, some non-TB ports and up to 64GB of RAM.
Shut up and take my money!
