I find myself needing to compose and edit Word documents and soon Excel docs. Will be simple stuff, nothing complex. Also using Dropbox to store the docs to be shared between iPad and PC. Looks to me like there are 4 different apps to work on Office documents, but does not look like there is a consensus. On a search the last topic on this forum was a few months ago. Any advice on some of the newer apps designed to work with office docs?
