I'm still awaiting the arrival of my iPad and was wondering how these apps integrate with the desktop. Do they go via MobileMe? Or just iTunes? I'm a bit worried as I have read a lot of reports here of people who have had the conversion process pretty much ruin their keynotes etc. So would using the iPad for 'work' simply mean that we would have to start, edit, finish, and somehow maybe print to PDF to get something done? Or present a keynote directly from the iPad as long as it was only created on the iPad? Or is there a MobileMe integration aspect?
