If anyone was inclined to, they could post a gigantic list of links to webpages where people talk about their issues with Windows 10 based PC's. There is no such thing as an OS or a platform that has NO problems whatsoever, a platform that is reliable 100% of the time for everyone. Mac OS X has had issues from it's inception (this certainly isn't a new phenomenon), and so has Windows. So has iOS and Android. There is clearly a driver issue with these 2015 MBP's, and I'm sure that Apple will fix it as soon as they can (probably with 10.11.5). Personally, I find my Macs to be as reliable as they ever were. I have no issues.
