the article is an interesting read, although i think the inclusion of the pictures does something to delute the objectivity of the article. don't get me wrong, i love pictures that leave more to the imagination than the give away, but it starts to come off as a ploy to generate traffic for your site.
and of course i begin to wonder if the designers of the vibrating controller were really out for improving our gaming experience through bio-feedback, or if they were thinking that people would want to put their controllers in their pants...
