I pre-ordered the new Macbook Pro 2016 when it originally came out. Here's my take after using it for more than 6-7? months (no clue, time goes by):
1) I am extremely happy with the butterfly keyboard. There is absolutely no issues with it for me and it's my ideal keyboard. I honestly do not understand people who say the accuracy is bad on it - perfectly fine for me. Use it for long enough and you'll get used to it. The only thing it is guilty of is being different.
2) I enjoy the Touchbar and TouchID, it genuinely feels nice to use it. ESC key being on the touch bar is something you get used to, but understandably if I was a huge user of VIM it would probably make me extremely upset. Thankfully I'm not and it works fine for me. I genuinely do not notice it anymore.
3) I ran out of USB-C ports on my laptop (4 total). I have pretty much all of them in use, so I now need to resort to USB-C <-> USB A hubs. For some reason, USB-C <-> USB-C hubs don't exist, so that honestly sucks considering I completely switched to USB-C plugs before I ran out.
4) Touchpad size is much better than 2015 MBP. After using this so much I could never go back to a smaller touchpad, and using my old 2015 MBP just honestly feels bad. It might be due to my sensitivity? I have no clue why people say their hands hit the touchpad since I have never had that issue in my entire time owning it.
5) CPU and memory is great. I can run multiple virtual machines in Parallels no issue. I develop games and constantly test them in the background. I really see absolutely zero drawback from the 2015 MBP, and even though on a spec-sheet the hardware /looks/ worse, in my experience it performs much better.
Take what you will from my experiences.
