I don't own an iPhone and believe it or not I've never owned an iPod. However, my phone contract expires at the end of June and I'm looking forward to jumping in with both feet. Here's what I'm looking forward to the most:

Turn by turn GPS. Anyone who has driven with me knows that my sense of direction is poor. A couple of months ago I actually started driving on the wrong side of the road- honking at people assuming that they were on the wrong side. Silly American.

Decent video. I'm also poor at documenting those parental events. If it's not a birthday or Christmas- the chances of it being caught on video by me are slim. I'm hoping it will have good integration with Vimeo- as that's my video host of choice.

Decent photos. See above - I use Flickr.

Gmail / Google Docs / Analytics integration. I could ditch the laptop if I had good access to this.

VideoSift 4.0 integration - er, maybe. Though I know Flash video still hasn't happened. Anyone have any news on when it will? Seems weird as it's available on most other smartphones. I can only think that Apple is worried that it would cut into App store revenue.

An iPod. Seriously- never had one.
