I used to work for Apple, for at least 3 years. Greg knows that. As for the hinges you can take it to an authorized repair center and they can repair the TiBook, but you are seriously better off buying a new machine.
The hinges were a problem, but that happens with excessive opening and closing. With a new machine the hinge goes across and you have a much larger HD out of the box. If you buy at an Apple Store, like the grove they will move the data for free with a new buy.
