Given the history of graphics issues (many of which where related to heat causing capacitors or GPUs to misbehave) I'm not at all surprised that their testing of heat-related issues is subpar to what you would expect. The fact they sell fan-less machines despite a history of heat-related issues in almost every solid-aluminimum-construction laptop they've released seems particularly negligent to me. EDIT: If you'd like more information than just heresay, watch some of Louis Rossmann's videos on macbook heating problems (the video on tantalum capacitors is particularly interesting).
