I was updating an old 2012 retina MBP to Mojave today and I forgot how awesome the magsafe connector was, the glowing apple logo on the back, the heft, the ports, the keyboard, the physical buttons instead of the IMO gimmicky touchbar. Imagine the components and cooling capabilities that macbook pros could have if they kept the old enclosure, got rid of the touchbar, redesigned the keyboard, made the trackpad bigger. You'd have a perfect MacBook in my opinion. You could also battery the heck out of it.
