I'm somewhat wary of jumping into an issue that is obviously extremely personal and emotional for people, but this remark struck me as odd:

  You can’t even resort to just hitting the home button
  blindly a bunch of times, because if you hit it too
  rapidly, the iPhone will interpret it as a double-tap.

What I find odd is that double-tap is the number one way that I launch apps. The author mentions the double-tap as if its a bad thing (in the context of finding an app to launch) and yet double-tap is the way to get to the recently-used apps to display.

I can't fault him on the other points, but this seemed like a blind-spot.
