It sounds like a lot of you guys want Apple to run 2 OS's on every device--Regular iOS and also a version of iOS that you are not "bored" with. Unfortunately, that's not how software works.
I get so sick of this conversation. The UI is boring because it's the first thing you see when turning your device on, and it's the last thing you see when you turn it off. Switch to another device and you will get sick of that UI eventually too. But how much time do you actually spend sitting there just messing with the UI? Do you sit there and swipe back and forth to different things and take notes on what you do and don't like?
My opinion: if the OS works, is easy to use, and gets you where you need to be, then who cares? You want widgets? Go to Android, or see what the new notification system is like in iOS 5. (I think it will largely solve a lot of these silly widget complaints.) Hopefully, it will let you dock weather conditions into it so we don't have to hear about that anymore. Android users seem to want to check their phones for weather forecasts at least once every 10 minutes because those weather widgets are really really important to them.
For those of you waiting for iOS to get more and more complicated to "keep up" with Android, don't hold your breath. It's not what Apple is all about.
