Pogue and Mossberg have videos which sum up their reviews. Baig has a sidebar which does much the same. All list the nearly same pros and cons, only Baig is more enthused about the iPhone 3G. All point out that the reduction in price is more than made up for by AT&T with the increase in the contract price. Remember, AT&T is not paying full freight for their supply of that iPhone.

No voice dialing, copy-and-paste, Bluetooth stereo audio or phone-to-phone photo sending (MMS), in their order of importance, will cause me not to upgrade, as I do not consider this an upgrade. I have worked out how to do two of the four. I just have to accept not using voice dialing till I can get that voice dialing software available for unlocked iPhones.
We have a GPs device and will likely have more. The iPhone 3G does not equal any current devices, it tells you were you are, not how to get to where you want to go.
Oh, the 2.0 software, which allows uploading 3rd party software, is available for existing generation iPhones.
Case made.
