It hasn’t changed much since then, but after reading up on the iPhone 4S and all the improvements, I think it’s more than a worthy upgrade.
Most nerds, tech pundits and the likes won’t recognise this for what it is, but the consumer won’t care. The improved camera alone will sell this to millions of people. Bringing the iPhone on par with the iPad 2 in terms of raw processing power is another thing consumers will only realise when they pick up an older iPhone or any Android device and experience the sluggishness of the UI in general.
