Ouch.
After seeing the touch bar, I think it's really not all that useful. I would much rather have seen more battery, RAM, faster CPU options, traditional USB and HDMI, magsafe, and more SSD. Basically take the 2014-2015 MacBook Pro and beef it up and I will be very happy.
People say it's selling. Of course it is. Mac still has a near-monopoly on "Unix with good UI." But if they keep doing this, it will erode. Windows is becoming nicer in many ways, MS and other PC hardware is getting better, Linux desktop is steadily improving, etc. The ecosystem never stands still.
