Until last year, Apple’s iWork suite was my go-to productivity tool on the iPad and iPhone. Then Microsoft released revised Office apps for iOS that matched iWorks’ capabilities, with the advantage of integrating nicely into Office 365 and OneDrive. I could now use the standard Microsoft apps on any device and work easily with the rest of my organization, across all the devices it supports.
Despite that remarkable progress in Office, I still have to use Keynote when I’m making a presentation, even if the slideshow was created in PowerPoint. That’s because Microsoft still doesn’t understand how to think about mobile users as well as Apple understands them.
