Hello all, I know the comparison of Office apps has been made in a few threads but with the updates from iWork and Quick Office and others, many of the reviews and discussions out there are out of date. I think my use case is pretty typical. I am in and out of the office and need to access and edit MS Office documents that are either emailed to me or are on my office PC. I can get to the documents on the office PC via Logmein or Dropbox typically. It is the functionality of the programs and their handling of documents that I am most interested in. I need to be able to round trip .docx and .pptx files primarily. I will receive them for review, need to edit or pass them along when I am done. Tracking Changes is a critical feature that none seem to have yet. Hopefully that will change. Using notes would be a good workaround for now. But the main thing is I need to import, see fonts and graphics as they were intended, and export so that the doc looks like it did when I received it. PPTX and DOCX. I do use Excel to review simple spreadsheets but nothing fancy and usually one tab. Yes the GUI is important to me but the round trip functionality is more important. So QO? Office HD? iWorks? Docs2Go(but worried about Blackberry's purchase and further development)? What have you folks with similar needs been using?
