In a rather bizarre situation reported on The Consumerist website, it turns out that smoking near your Apple computer is a bio hazard and voids the warranty.
There is very little doubt as to the repercussions of smoking a pack of ten per day, however one would never think it would affect a laptop’s warranty. If you have a Mac, it does. Two readers in different parts of the country claim that their Applecare warranties were voided due to secondhand smoke. Both readers appealed their cases up to the office of Steve Jobs himself, both lost.
