Weekend Fluff - iPhone +iWork?

Here is complete speculation and conjecture, but hear me out.

I think the killer app for the iPhone will be - iWork.

Let me explain why.

1) They new iWork is really easy and fun to use. And, Apple wrote it. Smooth, non-third-party development path.

2) It will encourage Windows people who buy the iPhone to get a mac for it all to sync together and have a seamless experience.

3) It takes iPhone from phone with a lot of great features into a true productivity tool. The experiences on most other mobile devices as far as productivity apps tends to suck, so something that is just easy to work with and can handle some very basic formatting would be great.
