You say, having never actually used it. How do you know it's horrible before trying it out?I don't think you've ever used a touchscreen display before. They don't need to constantly be adjusted because they get pushed back, and the difference from having to move your eyes and hands off of the keyboard to locate the touchbar vs a touch screen is going to be negligible. No, the touchbar is a keyboard that can change its keys, but instead of a mechanical keyboard they went with a touch keyboard. It's horrible for ergonomics and touch typing. it's good for my wife who watches Netflix, but then it belongs on their MacBook Consumer, not MacBook Pro.
Going into it with pre-formed opinions is going to affect you as well - if you expect it to be horrible, odds are you'll think that coming out. Some people just don't want to wait and give it a fair shake before passing judgement. It has all the potential to be amazing.
