Inspired by Joseph DeRuvo, here's a taste, along with some write-up.
Look on the left to the sub-sections for what detail I have up here so far.

FLASH - Turns out DeRuvo wasn't the first! Jeff Paradiso (http://www.jeffparadiso.com/) turned an orange 'toilet seat' iBook into a touch-sensitive tablet waaaay back in the fall of 2002. Wired covered the story back then and posted a few pics. It's intertesting to note that this is essentially the same path I took; keep the entire factory structure intact and just reverse the screen within the existing housing. All the more interesting because I was just saying this weekend that if I were to do it over again I just might buy the finished Trolltouch product (rather than a bare screen) and invert from there.

Jeff's story is at: http://www.wired.com/news/mac/0,2125,56086-2,00.html?tw=wn_story_page_next1.

and the pics are at: http://www.wired.com/news/images/0,2334,56086-5302,00.html.

And I just found out about him this weekend. Huh.
