Just one more to add to the other replies. When I'm developing, the Touch Bar is basically useless, but that doesn't bother me because having to use anything up in the FN "row" is an annoying hand stretch for me.

However, for all the other random apps I use (Keynote, Photos, etc) I LOVE the Touch Bar. Finding the particular operation I need up there without having to go to the menu/toolbar/mouse feels awesome.
