I'm about to get my first iPad. My wife, who goes back to the iPad 1, just lost hours of work yesterday to a corrupted file. In both our cases, the most important business-like use cases are word processing. Features we both want include: Doesn't rely on internet connectivity to work. Has an AutoSave that works. Failing that, has a really simple UI for saving a file (in particular, one that doesn't require entering a new file name). Has a Save As that works. Failing that, has some other way to make snapshots, preserving one version of document while one goes ahead and tries out further edits. Saves documents in a format that Microsoft Word is happy to read and write. We differ in how completely seamless we want Microsoft Word interoperability to be. I'd be happy to read/write .txt files, and have a separate program that handles .docx files well but suffers from other limitations. She wants something that plays nicely with .docx. Neither of us is relying much on formatting beyond basics such as italics, bold, and bullet points. Is there anything that actually meets our needs? Thanks!
