I'm a HD user on my 15" Rev A Ai Powerbook & probably spend an average of 10 hours per day using it as my primary machine for work & play. After a year's worth of use (right after my warranty expired) I noticed that the lower right corner of the deck just over the superdrive slot dips or is bent down from where my wrist sits as a type. It doesn't seem to be causing any problem with the drive, but I was somewhat taken back when I noticed what is undoutedly a structural fault with this design. Has anyone else experienced this with their machines & had any issues as a result with their drive? The salesman at the Apple Store told me this was the first he had ever heard of it, & seemed shocked when I pointed out that their 15" model on display suffered the same damage.
