I dislike this fact so much! You're correct of course, and this is the only reason I pay for a personal/family plan. I have no issues using LibreOffice myself (and anyone with whom i corresppond has no clue that I'm not using MS Office); but my partner and offspring have needs. My partner simply prefers office 365, and my offspring uses the school's web version for most work, so it is mostly out of convenience (and sometimes has to submit homework specific via MS Office)... Also honestly, the sheer amount of online storage PLUS the inclusion of the office 365 apps vs , say, dropbox is too compelling a deal to pass up.

As a side note, i dislike how schools tend to push students to learn Office (e.g. Word) sp specifically...I feel as though generations of children are being taught only how to drive a Ford Escort car, but will be confused the day that they have to use, say a Honda Civic, or heaven forbid a non-automatic automobile. As a tangent to this, while the following has never come up when I've interviewed job applicants for my teams...but if all things were roughly equal with candidates, and the only difference between candidates is that one only knows how to use Windows and Office, and the other one knows how to use Windows, and Mac, and Linux (or at least LibreOffice or other office suites, or some combination thereof)...I'll be picking the person who was able to use/learn more than just Windows/Office! </steps down from soapbox>
