But where Office Mobile really falls short is in working with Office documents. It can open pretty much any Word, Excel, or PowerPoint file, but it often can't edit them. Even simple documents like my office's single-worksheet Excel expense report often cause a Can't Edit alert box to appear when you try to make changes in them. Quickoffice and Drive almost always can edit an Office file, by contrast.
In other words, you can't rely on Microsoft Office to be able to work with Office files -- there's not even an option to save a stripped-down version of files that have some (never explained) compatibility issue. That's what makes Office Mobile pathetically bad.
I have to be fair to Microsoft: Its version of Mobile Office for Window Phone has all the same issues and limitations, as did the years-old version of the long-dead Windows Mobile platform. Microsoft is not treating Android (or iOS) users worse than users of its own Windows Phone, as Microsoft does to Mac users of Office. But the fact that the Windows Phone version is just as useless underscores how lousy Mobile Office is -- it's clearly not meant to be a serious office productivity tool, but instead a "yes, we support Office documents" check-off for naive buyers.
Luckily, you don't need Microsoft Office to work with Office documents in a serious way on your Android smartphone. Get Quickoffice or OfficeSuite Pro, and you'll have the Office you need.
