I'd guess the iPhone's about twice as big as the iPod Touch, maybe a little less. (Edit: I'm way off. The iPhone 3GS is 18 grams heavier than the latest Touch. Less than 20% heavier.)
But shouldn't the size be compared against other phones? I now the Palm is the same weight, and I doubt other hardware vendors could cram the same functionality into a substantially smaller or lighter package than Apple. I wouldn't mind if they made it a little thicker and packed in a bigger battery, but that's just me.
I think that podcasting is a perfectly adequate substitute for radio, and some stations have streaming apps available (warning: these chew serious battery and bandwidth). As for the camera, this guy says your camera doesn't matter:

The App Store is a big deal, and its relevance can't be overstated. Apple has basically positioned their platform to be the Windows of smartphones, with huge developer support. I heard there were 50,000 apps already available, and that number is only going up. It will be interesting to see if Palm or Android can attract the developer interest to compete with Apple in software.
