There are some catches. As Android Police warned, the current Android app isn’t optimized for tablets or Chromebooks. You can’t even use it in landscape mode. The iOS equivalent to the app is also nowhere to be seen at this point. We’ve asked Microsoft if it can elaborate on its plans.
This could still be a significant step forward for mobile productivity, so long as you’re willing to invest in Microsoft’s ecosystem. For years, both Microsoft and Google have insisted on separate apps for each task, requiring you to juggle those apps to get things done. This all-in-one approach might save you time if you’re working on both a report and the presentation to sell that report to your boss.
