I have a first gen MBP, and never had a problem with my magsafe connector (fraying, melting, etc.). however, I noticed the other day that I do indeed have a problem... see attached photo (this isn't my photo, but mine is similar). I never put tension on the cord, making sure to keep it straight. I dont have applecare, but I am going in to the apple store tomorrow to get a free replacement battery (mine is defective). what are my chances that they'll give me a new magsafe, or will I have to drop $80?
