Too funny! If only the OP had said that it was "a friend" who had the old PB, I wouldn't have suspected a thing! 😛
It brings up an interesting point, however. Do you think Applecare is worth it? It doesn't cover accidental damage, which is by far the most common kind of damage.
But how common is part failure after the first 90 days? If your Mac has a faulty part, isn't it highly likely the failure will manifest itself immediately, not spontaneously? I'm not saying spontaneous failures don't happen, but I'm wondering if they're frequency is so low that the Applecare isn't really worth it if money is tight.
I bring this up because I'm upgrading from a 5-year-old G4 PowerMac to a Penryn MBP, and it alone is all I can afford right now. I've needed a more current pro-level computer for a while now, but money is tight, and I'm going without Applecare, which I used only once, for my PowerMac within the first 90 days.
