I have an android device, where do you think the screens came from?
The people who dismiss widgets usually always post uninformed comments about them, such as "they're battery killers" (not all are) or "I don't need a big ugly clock widget" (that is not the only use for them...by far)
Even in this thread, people have only put down the widgets that iOS already has workarounds for. Nobody has commented on the useful ones such as the shortcut to the wifi options, or the four contact widgets that provide quick access to calling/texting favourite contacts.
I think the issue is that you are trying to suggest that what is useful for you is useful for everyone, and that clearly isn't the case. For instance, a shortcut bar to turn wifi/gps/bluetooth on and off would be completely redundant for me because I have no reason to turn any of those settings on or off. However, a shortcut to allow the control of music playback from the lock screen is incredibly useful, but iOS does this already anyway. Likewise, the ability to go straight to the appropriate app when dealing with a notification on the lock screen is also very useful, but again, iOS already does this without the need for a widget.
All you're really showing is how widgets make your life easier, and I think you're finding that that doesn't translate into how that can make everyone's life easier. For a lot of people, widgets wouldn't make any difference whatsoever.
