Just wanted to put in a good word about Apple. Not too long ago, my wife's macbook powercord melted about 1cm from where it plugs into the laptop.
She was quite distressed by this and I was surprised by the prevalence of this after a quick search on the topic. It seems that various people have had all sorts of experiences regarding how they were treated by Apple.
I did not have high hopes, but then my wife called Apple, talked to a representative, explained what happened and what the cord looked like. A manager reassured her and then sent us a new powercord that arrived in 2 days!
We sent the old one in, and are now even more pleased to be part of the "Mac Culture."
