I think that Microsoft office is a must for the new app store. I know you can view some of them as an e-mail attachment.

anyone know if they plan to do anything else? they need to if they want to win the business market, right?

Microsoft has certainly expressed some interest in developing for the iPhone. (why wouldn't they?)

But I think it would be very difficult to edit Office docs on the iPhone, although presumably less difficult than on other mobile devices. I used to have a Handspring Visor with a mobile version of Office on it, and it was VERY tedious, but usable.

Ultimately, I can't see how Office can not be on the iPhone, but it may take a while.

I would agree that having document editing capability is essential. I was fairly good at editing/creating office documents on my Handspring Visor ages ago. One would not try to do extensive work on such a small device, but if you already have an excel document created and laid out, then the data input is simple, even on a small device.
