Oh dear God no PowerBook, don't do this to me now dammit, not when I'm working feverishly on an essay on the Many Worlds Interpretation of quantum mechanics. Nooooo... My power cord, through perfectly normal usage, has been gradually wearing down. Today it became really significant, with the wires actually becoming visible. It's probably going to snap off imminently: Anyone has this happen to them? Where do I get a new one? How much? I need this quickly, and will pay Apple whatever the bloody hell they want me to pay.
