Office on iPhone

You can do it on Windows Mobile, Palm, and Blackberries.  What is it?

Edit Office docs.  I'm a bit torn on this issue.  There are certainly limitations to working with documents on a small mobile device.  I've tried it before, and perhaps I should have given it more of an effort, it was not really my cup of tea.

However, of all the Office applications I want the most has to be Word or Page.  I've sent megabtyes upon megabtyes of text already.  I can see myself sending more be it attachment or something else.

Editing spreadsheets?  Not so much.  I've used DocumentsToGo to create workout schedules and expense trackers but nothing really elaborate.  And in the end, I hardly used either.  But that has nothing to do with the spreadsheet app but more with my routine.

I don't even want to get into a Powerpoint-like app.  I find the need for a presentation app rather than one that allows editing.

Like to hear what you think about this issue and what your experiences has been.
