I ordered the 15" MBP Space Gray yesterday morning. The delivery date has been pushed back to 3-4 weeks now.
The Touch ID is a great idea, but then I have an Apple Watch which allows me to log on automatically anyway. Yes, I know it also allow us to use Apple Pay. But then most places I shop accept PayPal which has OneTouch set up (actually it is one "Click").
I am not sure if I like the Touch Bar or not. It is yet to see after some actual usage. If I were the designer of this thingie, I will put it closer to the trackpad, probably between the Space Bar and the trackpad, for minimal travel of our hands. Hey Apple, if you read and implement this idea, I want the credit. Ha ha.
Regardless, I think this is the best MBP ever made.
