For comparison and amusement:
(Marshmallow not shown here because it was just released on the day that these numbers were collected and was below .1% at the time)
It would be interesting to see comparisons of OS versions from the same year--e.g., iOS 9 vs. Marshmallow, iOS 8 vs. Lollipop, iOS 7 vs. KitKat, etc. I bet KitKat is what's giving Android its perceived edge, and if you only counted the last two releases iOS usage numbers would blow Android out of the water.
Excellent point. Plus, it doesn't look like Cook specifically called out Sorkin as one of the opportunists, so it's interesting that Sorkin got so defensive, seeming to identify himself as one of the targets.
Yeah, there should be an easy way (the Tips app?) to see a complete list of everything hidden. The "three dots" just mean "more options," so it makes sense to me that they would invoke different menus in different contexts. I think the three dots are supposed to be ellipsis dots.
