Here is Danny's Mac (it's actually a powerbook G4) sitting on his glass-top desk.

Danny was unaware of a battery recall, because his battery was not included in the original recall which he checked, and was added to the recall in a letter which was sent to him. Having checked the website, he didn't look at the letter to see that his battery had, in fact, been recalled.

Yesterday the battery became so hot that it cracked the glass below it. Apple agreed to replace the battery. Danny said he was sure that if he left it on it would have started a fire it was so hot.

Apple is not paying for the damage to the desk, but since they sent Danny a letter saying the battery is unsafe, I would venture to guess they are not responsible.
