I had high hopes for Dex when it was first announced and I was on android for my phone, but dragging around a monitor was more work than just bringing my laptop. I got a 12.9" iPad a couple years ago as a portable library, then last year thought I might replace my (Windows) laptop by adding a keyboard and mouse to the iPad so I wouldn't have to take both into the field for minor work. I've also got a Samsung S7 so I tested it out as well. The capability/usability gap between the full desktop version of Word and the mobile versions made me give up. Understand I have a dozen templates, from simple to complex, in Word, and around 20 calculation or tracking Excel sheets - so transitioning to Pages/Docs and Sheets/Numbers would cost me about $20k in productivity time. And I still wouldn't have my CAD, finite element analysis, or industry-specific utilities with me.
