Does anyone know if there are "office" apps for this?

I don't know about office but they have a Citrix App for the IPAD. YES, this is bringing mobile production continuity to a whole new level.

There is a mobile iWork available, on the full Mac version it can read and right MS office files check the app store to see if the mobile version can read and wright MS Office file formats

This is how I access Office ;) Citrix Ipad Receiver
