I don't repair these for a living, but I fixed my grandmother's computer, which was regularly exposed to her cigarette smoke. That dust inside you mention? Take that and mix it with tar. It winds up being a thick, sticky, messy, paste that traps heat and even more dust until things overheat and even short out. I wouldn't be surprised if that crap even caused fires. Truly, it must be seen to be believed.
Anyway, boo on Apple for this trick. Replace the unit under warranty and keep your customers happy. God knows they paid enough of a premium and can reasonably expect better service and consideration from Apple than for some $300 Dell.
