At 87% volume of the Pre, the iPhone also weighs 2 grams less.
If they hadn't packed the keyboard in, I'm sure your statement would be true, except for the 'very impressive engineering feat' part.
Is two grams really enough for a human to notice the difference? It's within rounding error - if given in ounce units both would weigh 4.7 ounces.
It looks like there's some chipping to the anodizing around the edges.. do you think it will be possible to open these without the chipping?
That's almost not a battery any more - more like a capacitor! What's really amazing to me is that they get 10 hours of music out of 73 mAh. That's progress.
