Just to play devils advocate (and because I might get a Bold when it releases)....what if the web browser and media capabilities of the iPhone aren't important to you? Now how does the Bold stack up to the iPhone?
I rarely use the web browser on my iPhone, mainly because when I am not in front of my laptop/desktop, I don't care to use it. I will say that I don't mind using the iPhone's browser when I need to, and avoid using the one on my Curve (I admit, BB's browsers are not great).
And as great as the media capabilities are on the iPhone (love watching videos), I don't have the need for it, I can do without having songs and movies on my phone.
My main thing, believe it or not, is the PHONE capabilities. I still make phone calls. I want a handset thats loud and clear (I have friends that speak low, I won't ask them to "speak louder" because they shouldn't have to, but my iPhones volume is low that sometimes, at max volume, I still can't hear the other person.). I used to use speakerphone all the time, especially when I was sitting in front of the computer and got a call. I can't use the speakerphone on my iPhone (its a 1st gen BTW, I haven't messed with the 3G version yet). I also get annoyed when I receive an MMS (pic or video), its just lame, thats all I'm going to say.
Email isn't awesome on the BB, I admit this. But what I don't like about the iPhones email is that I can only seem to attach one picture per email. Unless I am doing something wrong, this is annoying (had to send 5 different emails because I needed to send 5 pics to someone).
I always liked the little features about BB's that the iPhone doesn't have. I do like the blinking LED indicator, reminds me that I have a message or something when I missed the notification sound.
I like the physical keyboard, I make far less mistakes on it (though I am slower).
I like the side convenience keys, I use one for profiles and one for camera. Makes taking pics a snap and changing the profile from loud, soft, vibrate, off in a snap (sometimes I want vibrate when silent, sometimes I don't, requires more work on the iPhone to accomplish this).
I'm still holding off judgment until it releases and I can compare the 3G iPhone and Bold side by side, I want a 3G phone and one of these two will be it. I'm not jumping on either bandwagon until I hear more reviews and see them both in person.
