Not entirely certain what you're asking. But I think you want to know if documents created in iWork can be ported over to MS Office. And if that's the case, then yes. Documents created in Pages/Numbers/Keynote can be saved into MS Office compatible versions. Conversely, documents created in MS Office can be imported into their respective iWork applications. Now, there may be some formatting differences, so if the accuracy of translation is key, your best bet is to go with MS Office for Mac.
well were talking about 1,000 dollars for a mac with office over an iPad with works for under 700 dollars. If it can be easily transferred to either iWorks or MS office vice versa then that would definitely be the winner.
