Were they though? Having video adapters was always mandatory for me when traveling for work, since many places still only offer a VGA/DVI connections. Nothing has really changed in this regard with the 2016 model... the amount of dongles I carry around is still the same, but in total I need to carry less weight and volume, which helps.
The VGA part.. true that. I remember connecting my 2011 MBP to the monitor for watching movies on the bigger screen and needing a dongle and a cable. With 2012 above, a simple HDMI cable would have done it. Connection to projectors was always a no-show for these. hehe. In that regard, the 2016 above notebooks offer far lesser weight and other advantages that, like you, I appreciate, too.
