I tested the touchbar from a friends computer, just a few hours, I found out that doesn't works with quicktime 7, and the inconvenience of looking at the keyboard to find out what options are replicated is a waste for a pro user.
This super feature should come with the cheapest Macs, for people who prefer to use the trackpad instead a mouse or a wacom and prefer to move their spare hand and look to the keyboard instead of the main finger, those who a shortcut is just cutting their hair...
And this is talking about working with the macbook's keyboard, can't think who the hell uses his super macbook pro retina to edit video, 3D, design... without an external keyboard, mouse, screens set up (of course TB will be super super useful to low down the volume when watching a movie in the airplane...)
This is the hardware version of the Finder's "Cover Flow", who the hell uses it?
In this touch era, casual people is claiming for a well done "surface" (sorry micorsoft, you are the sole problem of my surface), and not to try cheat pro users with toys from the 90s.
