I've sold my iBook G4 on ebay but now the buyer is kicking off because one of the small rubber feet on the screen is missing (came off years ago). I've never seen this as an issue, and honestly forgot to mention it on the listing. He is saying he bought the machine because of it's portablilty and this is now comprimised!!! The screen closes, and the latch is fine - to me this is really not a problem, but he won't accept this! What does everyone else think - does he have a point?
