I love the new iPhone 4S. Super fast and extremely responsive when navigating through apps, browsing, games, etc. Of course, Siri is the huge new feature on the phone and it pretty much works as advertised. I give it a B+ so far but know that it will get better over time. Having to connect to the network to use Siri is a little annoying but it's manageable. And certain voice commands don't work too well like asking it to play certain podcasts that have similar names to songs in your library will more often trigger the playing of the song. For things like setting reminders, calendar meetings, initiating phone calls and having it read/reply/send text messages, it's amazing - to the point where my preferred method of doing these tasks is now via voice. It actually is faster and more efficient. One place it is perfect for is when driving. I've carried on full text conversations with people without missing a beat. Of course, you have to deal with the "looking crazy talking to yourself" issue. Still haven't quite crossed that hurdle yet so when I'm in the office or a public place, I go back to finger inputs. But the dream of Star Trek computer will one day be realized...
