A few days ago John Gruber linked to a Twitter poll where like/dislike for the Touch Bar was split 50/50:

If half your userbase likes something, you can't really call it a flop. But I'd argue you can't really call it a success if half your userbase dislikes it either.

While it's not really an Apple thing to do, the results of this poll suggest to me that Apple should make the Touch Bar an option, and not something you are required to get if you want a high-end laptop.
