Well, that's a pretty long time ago and in the last years, I have seen quite a few "things" which convinced me that Apple has taken care of this problem.
Matt Haughey mentions a "perfect" and shocking evidence for this on his weblog today. He writes:
A couple days ago, I was reading email when I heard a loud snap and my screen collapsed right in front of my eyes. The titanium metal snapped clear off the LCD screen, right above the left hinge.The picture of this incident looks as frightening as his story sounds !!
I've heard that the Tibooks were fragile, but all the stories I heard involved dropping it from height, slipping off a table, or dropping something on top of it. My Tibook was sitting in my lap when the metal just up and severed itself. I couldn't believe what I saw, but in searching around I found many, many stories of people experiencing similar problems. I expect things to eventually wear out, but I'm surprised a 2 year old laptop that was handled gently for its life would up and break in such a big way. I have read story after story about other Tibooks, some just a couple months old that suffered broken hinges from sitting on a desk.
While I write this piece also on an TiBook, I start wondering whether Apple went a little to far to make their dealers happy again... sigh...
