There was quite a kerfuffle over these machines, as they were retina (at the time, this means expensive), woefully underpowered, and basically required a dongle (also new then) as they had a single usbc port for all charging and IO. Also the butterfly keyboards failed if you looked at them wrong. Despite all that, I loved these machines, but many people found them to be just a bit too Apple.
