There are many iPad Apps that claim to be compatible with MS files (Word, Powerpoint, Excel). What they mean is that the App will open the file if it has the right extension name, but NONE of them are compatible with the formatting and mess up the most elementary formatting. The only one that does it perfectly is OnLive Desktop because it actually uses the latest Microsoft software (I don't know how they deal with the license problem!), but since the software lives on the Onlive server you have to be connected to the internet and you have to have your files on the Onlive server too -- so it's not much use to me, but it may be for you.
