Oh I knew about that   

Didn't think it was too major as they quickly removed the update (which was only bug fixes anyway) and released a new one within a few days 

Not being able to make a call and Touch ID not working due to the update - I call that very major
My point being, that it shouldn't have been released in the first place, no matter how many or few people were affected.

The v8.0.1 update also didn't fix the Wi-Fi and battery drain bugs but I believe there were work rounds to these while Apple continued to look for fixes.

This is the sort of thing you expect from MS not Apple. I hope Apple haven't lost their way, I think they have been a great benefit, pushing usability and styling forward
