1) Do you need multiple columns of data, column types, or the column summary options?

Yes for multiple columns and column types. Summary options are a great feature but not killer one.

2) Do you need formatting support? Or just plain text like OmniFocus for the iPhone.

Formtatting.

3) Do you need attachment support?

Sometimes.

4) Should it be a viewer only, or have editing capabilities? If just a viewer only, how well does the Quick Look preview/DHTML export meet your needs? (Viewing the export on the iPhone that is)

Editing, If it's a viewer I don´t need it.

5) What kind of syncing expectations do you have? This would be one big reason why OmniOutliner 4 needs to be developed first as OO3 is not designed for merging synced changes.

If I create a Outline on the mac y want to keep working with in my iPhone. For example, I leave my data on MobileMe or in Dropbox, so I can open it everywhere, Why not on my iPhone? A sync web like the outliner of CarbonFin is the best idea I've seen until now. I can edit my outlines in the web or in the iphone and export then to OO. But OmniOutliner for the iPhone has to be an outliner in all the ways.

Come on! develop it! And we'll buy it!!!
