What are the most creative an useful functions of an iPhone in the context of making your life and business better? Better meaning, simpler, easier, and more streamlined.

Personally, It has been a huge help when I am on the road and I need to review a rough cut. Since I can view H.264, even if I don;t have a wireless signal, one of our editors can send me a cut for approval and I can make notes and reply quickly. I have a program called airshare and I can use my phone as a wireless hard drive for transport and viewing of smaller quicktime movies, but I haven't used it for that yet.

also, I use maps when I am on the road, a lot.

I am not in love with the iCal interface. We use a productivity software in the office, and by next year it should be available for iPhone. I also get a lot of use watching movies and playing "Enigmo" on the plane.

I think we are a little ways away from having FCP on the phone (I kid).
