Some of the essays in here are really good, as well as informative and well drawn. Others feel incomplete and a few are simply illustrations, which might feel at home in a book of pure illustrations (though they aren't artistically good enough to hold up in that kind of collection). I enjoy comic art, but without accompanying words I don't think it's nearly as effective.

But, the good essays make up for the not so good ones. The one about the Dvorak keyboard is especially interesting.
