Today at its annual Google I/O conference, the company finally found a way to make its mobile office solution sensible. It announced several pieces of the Office puzzle that finally make its productivity suite something thats comprensible to the average consumer and a legitimate competitor to Microsofts Office suite on mobile. The first is that Googles presentation software, Slides, is now available on mobile. Like Docs and Sheets, its a standalone app that sits apart from Google Drive, which is mostly focused on storage now — though all four apps are still tightly integrated.
