A few other missing features on the iPhone: MMS messaging and easily sending contact information.
Yes, I can email photos, but not everyone has an iPhone that can check email. MMS has been on the phones I've owned for awhile, so how did the iPhone miss the boat?
As far as sending contact information, I'd be happy if the iPhone could automatically convert contact information into text and send it via SMS. It doesn't seem that you can email contact information either.
