I saw those numbers too. One question though. Are those fail-rates within the first year of purchasing? Because if not, then that isn't a fair assessment.
Think about it, the 2014 MBP's keyboards have been out there for 4 years now. A 5.6% fail rate within 4 years of life isn't bad. 6.0% for 3 years on the 2015... 11.8% for the 2016s within 2 years. And 8.2% for the 2017 in only a year?
Maybe those rates are for failure within the first year... But if not, it really does show that the 2016 and 2017 models are truly bad and that the 2017 MBP's keyboard might not be much more reliable than the 2016 in the long run.
Edit: Nevermind. I should've actually read the article. It does state that these are warranty services provided within the first year. Need my morning coffee... Please disregard my entire post.
