OK, the powerpage articles seem to indicate that it is the plastic outer ring, not the titanium parts, which is "delaminating". I thought the following text was interesting:
"However, he did say that it was entirely heat related and suggested I use one of the devices to raise the bottom of the PowerBook off a flat surface to provide ventilation. Makes sense to me. I'm expercting it back today or Monday and will purchase one of these."
I noticed when I used my PB on a table that the bottom got really, really hot, and that two of the tiny rubber feet were missing. I got some bigger rubber feet from Radio Shack for 89 cents and put them on. Now I have 1/4" of clearance below the machine and it stays much cooler.
