Just came back from an Apple store visit where they replaced my 4 year old MBP power charging brick because the magnetic end was pulling apart and was flaking in and out when it was trying to charge my computer. I had seen the class action lawsuit and stuff but that had already ended from what I could tell. I figured I would have to buy a new one but wanted to see what the genius bar would say. I went in for my appointment, the genius looked at it, went into the back room and came out with a new one. He had me fill out some stuff on an iPad, handed me the new power brick and told me I was all set. I told him how much I appreciated the service, shook his hand, told him to have a good day and walked out of the store with a brand new power brick at no charge!!
