iPhone 4 IOS 4.2 iPod play/pause button "size" (hitting skip forward/back)
With iOS 4.2 I find myself hitting the skip forward or skip backward button when I intend to press the play/pause button. This occurs in the iPod software or the quick controls that pops up when the phone is locked and you press the "home" button twice.
This is a big annoyance for me since I mostly listen to audio books and the skip forward/backward buttons move you between chapters.
I'm guessing that the addition of the AirPlay button reduced the size of the other buttons making the play button's sensitivity area just enough smaller to be an annoyance to me and my not-overly-fat fingers. (The AirPlay button is slightly wider than the old bluetooth output control button.)
