Then, there's the issue of exporting to MS formats. Some of my university papers require documents to be submitted in MS formats. When exporting from Libre Office, the result is a document that gets completely distorted opening up in MS Office. Spacing, formatting, indentations, layout get completely screwed. This cost me significant marks in the past with a couple of papers before I started arranging with lecturers to accept PDFs.
Yes, LibreOffice is a knight in shining armour. But a lot of the armour is more like tinfoil.
