Pagehand is a new word processor for the Mac whose native file format is PDF — yep, it saves its documents as PDFs. I’m not sure what I think about this. Whatever you write in it is immediately shareable across all platforms with maximum compatibility, and that’s good. But the documents won't be readily editable, which is not so good. I can see this being an attractive option to people who regularly need to print their documents and want those documents to keep their formatting — but how many such people are there these days?
