Have you ever worked on one of said machines? I have coworkers that get sick from just touching the nicotine-covered parts. It's disgusting to handle tar-covered components, and the smell is overwhelming sometimes. Plus, the warranty is voided by the damage caused by smoke in some cases. It is as good for things like fans and optical drives as it is for your lungs. Sometimes the machines are so gummy that it's basically a loss unless each piece is throughly scrubbed clean with solvent. I'm not exaggerating.

I work for Apple. You're out of line, Coward.
