The reviewer liked the product enough, but slated the fact it didn't have a word counter. Now, I for one, have never cared about the number-of-words in a document. But, it turns out, journalists tasked with writing a 2000 word review _really_ care.

Incidentally the solution is not fewer features, but better UI. Notice thats a very old screenshot of Word. Whereas Word to day looks very different, has the same (or greater) feature set, and a much more streamlined interface. The much-hated-on ribbon bar is actually a better interface than endlessly-deep menus and a million toolbars.
