> That said, in regards to established software like Microsoft Office vs LibreOffice, it's likely that there will never be full feature parity, but that's probably not some absolute dealbreaker for most.

At least for finance and insurance industry, the feature differences between Excel and LibreOffice Calc are are deal-breaker (users in these industries are often power users of Excel). I can also easily imagine that the same holds for Powerpoint vs LibreOffice Impress for the consulting industry.
