Well nothing's "wrong" per say, but since we're talking opinions here I don't think it was thin or light enough, I don't care for mag safe (I'm generally careful where I put cords and find mag safe annoying if anything), actually like the new keyboard better (though I don't care for either that much), and much prefer having 4 interchangeable USB-C/TB3 ports that I can use for anything (video/audio output, midi, external storage, power out or in, etc). Sure I have to have a dongle or two, but I've actually found that to be not a big deal and overall pretty nice. And that's just the things you highlighted, not mention other things like the better touchpad, better speakers, brighter screen, finger-reader, etc.

I mean I get why people have preferences for the things you mentioned, but I'd call them appeals to "comfort and familiar" not "state of the art."
