Apple needs to start asking it's customers if they are smokers BEFORE selling them the product, and refusing to offer it to smokers BEFORE taking the cusomer's money. In fact they should put this in all of their marketing materials. To do less is pretty fraudulent. If they are not going to honor the warranty based on the habit of smoking, then they should have to refund the price of the machine and any extended warranty that was purchased.
Apple doesn't want to subject their techs to tobacco smoke residue? Fine, stop taking money from smokers and give back what it has already taken. It's that simple.
Do you think a smoking customer would buy Apple's product knowing that the warranty would be void as soon as they light up a smoke?
I wouldn't, but then I don't "think diffrent" like those Apple users claim to.
