Word certainly is, at least on OS X.  Within an hour of my first time using it in a decade last week, I caused it to beachball for five minutes straight by clicking a single button (select all text of a given style).  It then took me over an hour to figure out why my TOC entries had no spacing between their numbers and titles (hint: it wasn&#x27;t the spacing setting), and another hour to figure out why, after I &quot;fixed&quot; the spacing issue, why my chapter numbering was all messed up (the &quot;solution&quot; was to reformat each chapter heading with the same format it already had).<p>It has terrible default orphan&#x2F;widow control, and editing anything graphical is a royal pain in the ass: the slightest wrong touch can throw your diagram into disarray.  Those that &quot;know&quot; how to use it I&#x27;ve noticed seem to have near-infinite patience and knowledge of where all of Word&#x27;s &quot;land mines&quot; are and how to avoid them.<p>People use it because it bundles in every obscure feature under the sun, so it&#x27;s effectively the lowest common denominator when it comes to meeting an organizations&#x27; needs.  And for those who already know how to use it, I suspect the sunk cost fallacy keeps them there.
