Also, I tend to use it to drive my stereo in the car which means I want to use it while driving - the screen presses require pin-point accuracy making this impossible, or at least unsafe enough to prevent me from doing it.
Yeah, this is the only thing I miss about my old mp3 player with real buttons (which are now a sin to put on portable consumer electronics, right?).

I don't care much about Siri; it's kinda neat, but not a feature that sells the phone for me.

What I like most is simply the stability/dependability. Maybe I just had rotten luck, but my previous smartphone (Palm Treo) had issues. Like crashing upon incoming calls, randomly reassigning custom ringtones amongst contacts, crashing some more, touchscreen being slow or unresponsive, etc. I hate the "it just works" slogan... but it does, and I appreciate that.
