Ashley Nelson-Hornstein (currently an iOS engineer at Dropbox, formerly at Apple):
I forgave iOS 7 because I understood the incredible amount of work accomplished to pivot the platform in just six months. So for me, iOS 8 is my first real opportunity to be concerned about the state of the platform, and not evidence of a pattern of issues. I’ll be justifiably concerned and worried if the same software quality issues are being discussed in 10.11 and iOS 9. Until then, I’m willing to give Apple the time necessary to let their plans propagate.
