The reviews seemed a little weak for the most part. But I think that's because Apple has more competition now, so the iPhone isn't the best at everything anymore. Other platforms definitely implement certain features better IMO. Of course I still think it's the best platform out there, so I'm still anxiously awaiting my 4S, after using the 3GS for the last 2 and a half years. But I definitely think Apple will have a lot of catching up to do by the time next October rolls around, assuming that is when the "iPhone 5" comes out, because the other platforms are moving fast. Based on the reviews, it seemed like the iPhone 4S was "catching up" to the other devices in some facets, and surpassing them in other facets.
