I travel a lot for work and would love to just bring my iPad and keyboard on trips. Right now I have to bring my laptop with me as well so I can view and edit .docx and .pptx files for work. I have been searching and researching D2G and O-HD as well as others but have not found any recent reviews about their capabilities. Before I spen $20 on an app I would like to know if there are any users out there of these apps who could provide some insight. I need to be able to view and edit these types of documents and when I return them to people the formatting needs to stay intact when they open them in the full desktop version of MS Office. I've tried Pages and Keynote but they do not maintain the MS Office formatting. Any help?
