The headline could just have well been, "Former Apple Employee Believes Touch Bar Should Be Standard Equipment on All Macs"
I've only messed around with Touch Bar at the Apple Store. I found no reason to dislike it, but haven't lived with it, so I don't know how it might really affect my work and play (though I do a lot of clicking and dragging of sliders while image editing, so I can't imagine how it wouldn't be helpful).
Part of me is shouting, "Making Touch Bar optional would have been like offering the original Mac without a mouse!" Touch Bar is Apple's attempt at integrating touch screen with the Mac in a practical manner. I do not think touch screen is practical on a large, vertical display - lifting my arms all day might be good exercise, but that's about all. As a touch-typist, I prefer to keep my hands on the keyboard as much as possible. While reaching for my mouse is second nature, if I'm using that mouse to reach for a slider... I'd much rather the slider was right on the keyboard, where I can reach it by extending one finger. With Touch Bar, it can be.
I think Touch Bar would be a $100-$200 option, if it was optional. It would likely be sacrificed in favor of larger Flash storage or better GPU/CPU, meaning adoption would be much slower and fewer pro apps would be modified to take advantage of it. Arguably, power users are most likely to need/appreciate the potential productivity boost that comes with Touch Bar. Forced adoption may not be pretty, but I think it's a strategic necessity. If the power users find it beneficial, then the rest of the world follows. If they don't, Touch Bar goes away altogether in a few of years.
