Reading all these forum threads on MR and elsewhere, you start to get the feeling that every MB or MBP arriving in users' hands is defective and plagued by the heat and/or whine problems. So does anyone have an MB or MBP that runs merely warm (or cool when idling)? And doesn't whine or moo? And isn't in denial about genuine problems? I'm partly concerned because I've bought an MB for my grandparents -- their first intro to computers, ever. And I'm dreading the thought of their first experience with computers (and Apple ones at that) being filled with long phone battles and trips to the nearest Apple Store to fight for repairs. Is there any hope for them not getting a roasting, whining Rev A?
