Microsoft Word. That's literally the only thing which stops me from installing Windows on all of my friend's and family's aging laptops. LibreOffice just isn't capable of 100% replicating the formatting of a docx generated by Word, which for most people is a deal-breaker. (For me it's not, but for non-techie associates it is.)
I just don't understand why there's not more pressure on MS to port Office to Linux in exchange for them extracting so much value from Linux for their proprietary operating system.
