How about Pages?
Sure. It just depends on how complex your formatting is. You can also export it as a Word document. For some things, like outlines, you shouldn't see any differences. I suspect complicated footnotes, embedded multimedia, etc. would not survive the import > conversion > editing > conversion > export process well. In my experience, Pages is great, and as an added bonus it is the only app (that I know of on Android or iOS) that will allow you to both edit existing footnotes and create new ones. This is a big deal if you plan to use your iPad for writing papers. I wrote most of my dissertation on the iPad with Pages (using the bluetooth external keyboard, of course).
