I love gimmicks and thought the TouchBar was cool. Then I thought about it how I would usually use it, and the answer was "close to never because I touchtype". Then I realized that the ESC key that I use for so many things blindly is now more awkward to reach. Then I realized that the TouchBar doesn't have haptic feedback which makes precision work more difficult. Then I realized the coming version might actually have haptic feedback and force touch.
Then I realized that the MBP is still limited to 16GB RAM max. If I buy this machine I want to use it for 6 years to come. 6 years with 16GB RAM doesn't seem realistic.
I am not a negative person and absolutely love my Mac. I love the apps that I own and I can't wait to get my hands on the new Final Cut Pro. But I don't know if I want to buy another Mac. Remember when everyone told you the 15" MacBook is effectively a desktop replacement? That's what I want. A desktop replacement for work that I can also put in my pocket and carry somewhere else.
I absolutely don't mind buying 2 Macs. One portable one (12") and one semi/non-portable one for the heavy lifting. But right now that doesn't seem to be the option.
For example: The new FCPX is amazing! But it requires a lot of specs to deal with the ever increasing resolution. It's highly possible that phones can soon record 6k footage in <6 years that need to get edited somewhere.
