WordPerfect is superior to Word
To add to bigsteve666's comments, WP is vastly superior to Word not only because of Reveal Codes (an excellent feature), but some others as well.
My experience is based on WP 2000 (!) and Word 2000 and 2010... WP does not try to nanny you in a number of formatting/layout features like headers and footers, and list numbers and bullet points. A number of things are just easier to do in WP...
Of course Word does not try to be compatible with anything. Why bother, when it dominates the word-processor market?
Somehow I am reminded of Betamax v VHS in videotapes...
The good thing about Word and, indeed, the other MS products is, that they have created what is, in effect, a world standard, so that I can be pretty sure any of my correspondents anywhere in the world can open my documents and (at least to a large extent) see what I see.
Just a pity that it isn't WP for word-processing...
