This has to be the most bizarre excuse for voiding a warranty ever, but according to The Consumerist at least two Mac owners have been told their Applecare warranties are no good because they smoke.
In both cases, we are told, the Mac owner concerned took the matter up with the Apple supremo, Steve Jobs, or at least with his office. And in both cases they lost that appeal.
According to one of the users, who had an overheating Macbook, his machine had more than a year of warranty to run but the Apple Store called him to let him know it would not be working on the machine and his warranty had been voided. The chap says they told him this was due to the health risks of second hand smoke.
The other user, in a different part of the US entirely, reports a similar experience. She had a non-working iMac with an extended warranty which was voided by Apple due to contamination. When pressed for an explanation the user was told that the computer was contaminated with cigarette smoke and as such constituted a bio-hazard.
Oddly, the Applecare warranty document itself does not seem to mention cigarette smoke as being something that would void the cover. Apple has a long history of making mad decisions (see here, here, here and here for some examples) but this really does take the biscuit.
I'm an ex-smoker myself, and like many ex-smokers I hate the smell of cigarettes and I hate being in a room full of smokers. But I'll tell you what I hate even more, and that's some numbnuts repair guy who mistakenly thinks he will get cancer from looking at a hard drive with tar on it, and some numbnuts company which defends that decision.
