The irony is that not a single person on this planet complained the 2015 was too thick. I haven't met anybody online or offline who said they wished it was thinner. Yet they trimmed it down along with the battery.
I am a person who wished the 2015 MBP was thinner, closer to the light portability of the MB. So now you've met a person online on the planet or wished the machine was thinner, and I'm afraid to tell you, there are many others who feel the same.
Now yes, I and many do not wish for paper thin and light at the cost of significant decrease in performance or battery life. But people who say no one wanted x feature on the planet, I always find funny since it's more the author saying they don't want x feature and they can't comprehend that others who want something different than their own use case.
I've had the MBP with touch bar (and nearly every MBP / Powerbook since then), and so far haven't experienced any battery issues. Yes, my computer gets no where near 10 hours, but as a pro user, real life battery life has never been near those numbers except when on a plane simply watching a downloaded iTunes movie. So perhaps the battery issue is a quality control issue, affecting some but not all users. Hopefully Apple is able to offer a repair program for anyone affected.
