Ever tried getting word docs into Indesign without converting to RTF as an interim step? This may not be a MS problem and may be Adobes fault, but whenever I get a .doc, importing into indesign directly makes my life miserable for too often. Even if it doesn't crash Indesign, it often causes strange behaviour and bizarre formatting issues.
Between that and the damn paper clip wizard man of old, my Office suite tolerance is about zero.
But LibreOffice, ouch. After this last week, one more 'java update required' popup and I might start crying. I DID IT 1 MINUTE AGO.
Users expect their office suites to crash, but that doesn't mean that we as developers shouldn't be constantly trying to improve our code.
