Daughter was charging her nook color last night and after about an hour heard a sharp cracking sound. When she looked at the nook she saw that the cable end had cracked open exposing the electronics inside. Found one small piece of the plastic on the carpet about 3 feet away. - No apparent damage to the nook and I called customer service this morning and they're sending a new cable free of charge. I asked the lady if she had heard of this happening before and she said she had not. Oh well, no harm done and new cable on the way.
