Ehh. I've played around on the Android stuff, but for some reason the iPhone always winds up sitting most comfortably with me...
I just went from a broken down, falling apart 3GS to a 4, and expected the experience to be more world-shattering for some odd reason, but the biggest impact it's had on my life is actually charging up reliably when it's plugged into the wall...
Sort of like when I got excited about the iPad, then realized that having a laptop and an iPhone at the same time completely left me with nothing to do with it. Or when I updated to the new iOS and realized that there was not much there for me either (and it messed all my apps up, taking me two hours or so to sort out). Apple makes excellent tools, but the glamorous aspect of them that prompts fake hipsters to be able to actually "hang out" in an Apple store eludes me.
As for the 4S, I doubt I'd use Siri much, would appreciate the extra power, and lament the day when my 4 won't run the latest apps, like the situation I was just beginning to attain with the 3GS. Still hate iTunes more than even god could
