I like Apple too - writing this on a 2013 rMBP. Works flawlessly (touch wood).
But the new Pro series is just not pro enough for me. Why the hell should I buy a dongle for everything? It's supposed to be pro - you shouldn't have to basically carry a whole bunch of dongles to get stuff done. I don't know, maybe I am technophobe, but sometimes taking away the stuff which works and useful to shave a mm in height is just stupid from my perspective. If I want a super light laptop without the need for ports etc. I would go for an Air.
Dunno what's going to happen but will stick to my 2013 till it literally won't work anymore.
