Honestly, i was about to say something in the same light. iOS 8 has been nothing but garbage.
With all these bugs, I'm pretty surprised how there is no jailbreak yet for iOS8.
Apple only sells a limited amount of hardware compared to most companies. I have no idea how they're unable to test stuff like this before release. My iPhone 6 Plus has never been able to pair to any bluetooth device that I've tried, aside from my iPad showing up in the hotspot area complete with battery level, etc. I think that uses bluetooth, but I'm not certain. I don't use bluetooth very often, so I haven't complained much, but I could see how this would be really annoying for some people.
You should probably use a few Windows machines and devices to experience the hell that comes with them before you start chastising Apple over something minute.
I'll take these minor issues over that ANY day.
