My theory is that was a leftover from when they were IBM and had huge contracts (think along the lines of 40k laptops at a time). So if something went wrong and you pissed off the wrong guy at one of those companies they would hold you to the 'fixed by the end of the next day' part of the contract. So IBM took care to make sure that did not happen. When they got bought out I was pretty sure that quality would slide eventually to the bean counters.
