I think they <i>are</i> connected.  Part of the reason people are so comfortable with the iPhone is they really can't screw it up.  They can't download any apps that are spyware, or viruses or are going to steal their credit cards.  They don't have to worry about what attachments they can and can't open.  The very locked down nature of the device means it's a controlled environment that you can turn people loose in and say go nutz.  That most certainly is not something you can do with an open computer.<p>So I don't think you can separate the environment from the equation, it's part of the entire end user experience.<p>Personally I think it's putting the onus back in the right place, which is on developers to make things work and make them work dead simple.
