I have used LibreOffice Writer with <i>some</i> success, and Calc with more limited success, but in the latter case, perhaps just because I am limited with spreadsheets.<p>Writer is a problem in that it is a straight rip-off of Word, which supports the same file formats, but which is not fully compatible with Word.<p>Word and Writer handle styles differently: glyphs change, despite availability of the same fonts; alignment changes; tab stops are all over the place.<p>They handle images and floating things differently, sometimes placing things on different pages or behind other objects or text. Word online makes this even worse, because it doesn't handle image captions properly, and converts the image and the caption to a second image.<p>I get all sorts of weird problems with Writer and Word - no particular blame attached - and unfortunately the answer is always the same: do your work in native Word on Windows, unless all your work is going to be in LibreOffice.<p>I think that the basic premises behind modern word processing are just wrong, and it's because Word is so ubiquitous that everything else has to follow it. I think there is a space for a new style of WP which takes nothing from Word, or Writer, and which lies somewhere between that point and professional typesetting wares like LaTeX or InDesign; something which does less more professionally.<p>But it's just a dream, and it doesn't really take into account Excel, which is Microsoft's killer app and probably the keystone of the company's entire business.
