Please let's not start with this nonsense again. You're in love with the *idea* of the new MBP, and that's about it. Better see it for what it is. Ive & co are building products for scenarios their users don't live in. Yes, sometimes you need to take large steps to push people along. But this is leaving your users far behind without even tossing them a rope.
I am using an iMac and a MBA. Unless Apple computers suddenly start exploding on me or something, my next desktop will be a Mac. My next laptop will be a Mac. The ramifications of this change will eventually cascade down to me. I am every bit as invested in the Apple ecosystem as any of you here.
How are users left without a rope here? Adaptors exist. USB C peripherals exist. Bluetooth accessories is a thing.

has never been more apt, imo.
