While it's not as bad as IE was, I've come across enough bugs in iOS Safari that I have to agree with the author that Apple is purposefully dragging its feet.

Here are a few that I have personally run into:

As of Safari Mobile for iOS 7.1.2, tapping a clickable element causes the element to enter the:hover state, and the element will remain in the :hover state until a different element has entered the :hover state.

All of these bugs combine to make it very, very difficult to create a native feeling web-app on iOS.

Good point. On the new Facebook app they've put the scroll-up bar on the bottom, which is less intrusive.
