The lack of a replaceable battery is what keeps iPhone users from ditching their iPods all together, has very little to do with aesthetics.
I wont use my iPhone as an ipod or dedicated video device in fear that I will run out my phone battery.
This just solidifies my decision. My wife and I will stick with our first gen iPhones and family plans thank you.
When an iPhone comes out with a video chat and/or more desirable features other then speed and gps I will reconsider...
