There appears to be quite a few people on this forum who are concerned with their Macbooks' high temperatures. In most cases, it seems that there is no need for them to worry. However, I haven't really been able to gather what the ultimate concern is, should a laptop run too hot for too long. I mean, specifically, what might go wrong? And in what sort of scenario might this happen? Anyone with first-hand experience with such a situation? Sorry if I seem clueless. I'm a long-time iMac owner, but have never owned a laptop. I'm just trying to gather as much info as I can about the MBP's before I make a purchase. I'll be using it for editing HD video in Fincal Cut Pro, as well as working in Logic rather extensively (ie recording 8 tracks simultaneously). Got my eye on the 17" i5. Thanks!
