OpenOffice Writer and LibreOffice Writer have their proper bugs of their own, to the point that it's very frustrating to work with a non-trivial document. Many of these include some aspects of formatting not being saved to file and not restored when re-loading the file. And this is saving to .odt and not .doc or .docx. The Calcs have many bugs too. I have reported some but have since given up. For serious work I return to Word.
The other alternatives are not better. A couple of weeks ago I needed to create a catalog of products that is just a few pages long. Calligra couldn't even show the image I added; there was bounding box which could be moved around but no images were shown. Abiword got glacially slow when adding a ~4MB image.
My guess is same argument as adding blood type to ID: it could help you in situations like emergency or accident (checking blood type is a few seconds anyway, but there might be situation where a test kit is not available when needed).
Wow, I wonder how you got by. I'm useless when I had -2 or -3 myopia: couldn't recognize people's faces, couldn't read signs. With -3 I think your computer screen even looks blurry.
