Seems to me like you are the one complaining, not iPhone 4s owners.
I'm a 4s owner and this upgrade is amazing, you are smoking something fierce if you think other iPhones were a bigger upgrade than this time.
What exactly is amazing about it?
Let's see LTE, nice but not amazing since for me the ipad3 has it.
Better chip and camera, OK. nice but not amzazing again. Just a cycle update.
I am disappointed by the screen change, just taller not wider, blah.
I am keeping my 4S, but my wife's crapberry is gone and she will get this new iPhone5.
The the iPhone 4 to 4S, I am not impressed by Apple's update. Nice but the form factor is not an improvement IMHO. The extra speed will be nice but nothing else is that important to run out and get.
The Siri improvements will be nice in the stock iOS.
