It looks like there are going to be no winners and no losers to this debate. So, I figure I'll throw in my last comment and be done with this.
I should preface my comments. I own a 3G15 and I like it. I got it when it was the middle (not the base), so it came with the dock. Anyway, I find that the dock is useful for those that want to have a quick connection to whatever the line out is connected to. I currently have my computer speakers connected to the dock, making my day one long music festival. So, I personally find not including the dock with the Photos to be silly - they are the tope of the iPod line up. It's a luxury thing, if you will. But, not including them is fine.
As for the USB/Firewire debate. I don't have the USB cable. I use the firewire. My fiance uses the Firewire (via my adaptor for her PC) for her 4G because the USB port doesn't like her iPod (but it liked her old mini - anybody think they can figure that out?), but I mentioned that in an earlier post.
What the debate seems to be is why the Firewire cable is not included. To answer those who suggest that a cheap alternative be purchased, I (along with several others) have reminded that the iPod uses a propriatary connection. That makes the generic cable useless. There was that "dock anywhere" adaptor that I saw at the Apple store, but it was $10-15 or so. Anyway, it is an increased cost. Now, the opposition makes a valid point that if you can afford an iPod, you can afford a cable. I agree with that. But, if the iPod is the theoretical BMW of mp3 players, I don't see BMW charging more for vanity mirrors or air conditioning. I mean, you can get by without them, but they are touches that make sense.
