Well, after putting the 4S through it's paces for two weeks, I decided it wasn't the phone for me. What it really came down to is the display. Yes it is super sharp, but it's also a bit small for these old eyes. I was upgrade eligible on Sprint (EVO 4G user), and I had an iPhone on AT&T (3G) awhile back before switching carriers. I remember after switching from the 3G to the EVO thinking, "Dang, how did I tolerate that small screen?" Well in the end, I just couldn't live without the larger screen. I liked the iPhone for Siri for sure (though I often found her "not available"), and I hope someday soon similar technology comes to the Android platform. I also missed the seemless Google contact/mail/calendar integration since I am a PC user and use these for all my scheduling and contacts. If/when the 5 comes out with a larger screen, I will give it a look for sure! Everything else I liked about the phone. Wound up going to the Motorola Photon, mainly because they have a car dock for the GPS functionality and it's one of the biggest/fastest androids out there. I have to say, I really like the phone, and putting it into the car dock turns in into a GPS with turn-by-turn directions (Telenav). Pretty slick.
