Yeah, the first iPhone OS was well thought-of and intuitive, but after that it just relies on the user having to know some secrets to get it to work, e.g., who would've figured out that double-tapping the Home button on the lock screen would load Siri? That to move icons, group or delete apps on the home screen you have to hold them until they wiggle, and to group them you have to drag one onto another? Intuitive my butt...
Not that Android apps are any better. On some apps, hitting back actually means "go to the previous screen", even if that means leaving that app. But on my music player, if I load it, it goes to the "Now Playing" screen, which is the least useful screen since I can pause or skip songs on that screen, but I can do that from outside the app as well, so why would it show me that screen? Ok this is just nitpicking, it can't read my mind. But usually I open up the music app because I want to load up a different song. So I press the music app icon, I see the "Now playing" screen. Let's see, how do I see all songs? I press the menu button. No such option. I hit back. Ah, there it is. Real fucking intuitive..!
