Word and Excel etc. are legacy junk, held back by lost source code and fragile code, however much Ribbon fart you dress them up in; I really can't be bothered with PowerPoint. Example MS Office fubars includes modal dialogs * which lock all open Word documents, and the pathetic inability to have two separate Excel spreadsheet windows open and visible at the same time; yes even in the Ribbon version of Office !
* Haven't these MS Office developer cretins heard of multi-threaded code and concurrency? Many other developers sure have and produce even small applications using it!
LibreOffice may have some bugs in it but the GUI does support concurrency and has some features which shame MS Office. I've had no choice but to use LibreOffice on occasion, because I really do need to work on more than one visible spreadsheet at a time!
