I didn't know about the no-throttling thing; that could be useful for some. My use cases mostly involve performance spikes though.
However, I see 16 GB non-upgradeable as a severe limit on performance and expandability, and non-upgradeable drive as a limit on storage and expandability.
Sure, you can compensate for everything except the RAM by hanging stuff in a harness of dongles around it (if you remembered to bring them), but it is often not *practical*, which - in many forms (connectors, wire lock, physical function keys, oversize cursor keys) - is an aspect that they apparently haven't discovered yet for their list of what pro users are interested in.
Meanwhile, I wonder how many pro users requested the touch bar and how many pro users requested the removal of USB (and possibly HDMI) connectors, and the ability to upgrade the memory and storage.
IMO, the new MPB is an impressive engineering job. I really mean it. But as a pro user I can't help being disappointed that the marketing department have limited what could have been a wonderful, no compromise work tool in favor of gimmicks.
