I bought a new 17" 2.6 Ghz Santa Rosa MBP in July and it's spontaneously "blue screening". Ok, Macs don't blue screen, but there's that dark curtain that falls with the message that you need to turn physically reset the computer. This has been happening consistently for a while now. The laptop will just be sitting there idle and that curtain will fall. What the heck?? I run my MBP pretty hard. I'm wondering if it has overheated to the point of damaging something.
