What in your opinion is the best app to use when working with Word, Exel, and PowerPoint? I'd like to be able to upload, edit, and also download back to my Windows desktop if possible. I've searched for a few but can't really decide on which to buy. Either the iWork Suite, Office2 HD, or Quick Office HD. If there is a better one that I don't know about or if one of these three stands out as the best then please let me know. Thanks very much. Happy to be here.
