I just went by an AT&T store and tried out the 4S. Obviously, there is no real reason other than Siri for 4 users to upgrade to a 4S. Personally, I will be skipping this release for this reason. I think Apple did this to keep attention and remind everyone they make the best phone on the market. I was very shocked at how accurate and useful Siri was. It clearly recognized everything that I threw at it. I even said "T.J. Maxx", and it heard what I said and formatted it just as the name would suggest. In other words, instead of returning "Tee Jay Max", it was smart about it. This pleased me. I think Siri + iPhone 5 is going to be amazing. Siri was very integral and essential feature that the iPhone needed and Siri is something the iPad needs desperately. Before Siri was released, I was thinking that the iPhone/iPad needed a better way for input other than having to type everything. Even though the iPhone has the best virtual keyboard on the market in my opinion, it is still a meticulous job sometimes to input exactly what you want. Anyway, just wanted to share my experience.
