I disagree about YouTube; I love watching video on my iPad. I have no opinion of widgets. And he's completely wrong about multitasking; as an iOS developer and iOS user I think the iPhone's approach to multitasking is marvellous.

Other than that, it's all true (although, my mom seems to think that the iPhone auto-correct is great).

I think everyone should own an iOS device. I think the iPhone generally represents the highest-quality hardware and software that's currently available and I often recommend it to people, but it still does not come close to replacing my Blackberry as an email and messaging device, for exactly the reasons he mentioned.
