It is true what maflynn says though, people were clearly expecting something more — which frankly baffles me to no end, as anyone even remotely familiar with technology can see that Apple and their suppliers have pulled off an incredible technological feat.
but, if you're referring to TouchBar with 'incredible technological feat' I think a lot of people beg to differ, by either not liking it but needing other features (4 ports on 13" or a 15" screen period, for example), not liking it and flexible enough to go to the Windows world with good hardware too, or opting for non touch bar..
It is cool its touchID, has its own processing chip, and an OLED bar in the keyboard thats dynamic in nature, and is a cool engineering feat, but its not really enough to wow people by itself, it needs to be ADDRESSING a problem people have with their daily work flow that this solution actively resolves. It's been deemed somewhat gimmicky by some people. Not all, but a notable amount of distaste. I'm part of that camp, $300 more wouldn't have killed me but I didn't see the value in it nor want it as it stands now (nor want a non-physical ESC edition). There is potential but I dont want to buy on potential alone. I'm doing just fine adjusting brightness manually instead of using a glide gesture.
If anything, touchbar reveals a gap in the Mac. They want to incorporate touch, but keep dismissing touchscreen enabled Macs and say it clutters both segments too much,
What about Nintendo switch? Capturing home console and portable in one. The verdict isn't out yet on how that will pan out, but MS seems to have carved out a nice market of happy customers enjoying Windows world with touchscreen overlay.
Mac is in a weird spot.
..with iPad for example, it was a magnificent engineering feat (even though some dismissed it as just a big iPod touch which I was part of the camp for, and still maintain to a way lesser extent, but the overall package and experience transcends just being a big iPhone, otherwise I wouldn't love it as much as I do). it resolved lugging a laptop around, needing a fan based computer with crap battery life, just to browse and check email. Jobs always said no market surveys because people dont know what they want but Apple does.
Here, I dont know that Apple does know what people want.
Inflated expectations have always been the status quo with Apple's customers too, that's not unique to this iteration of products.
