I got a new charger under AppleCare a year and a half ago and the cable has frayed yet again at the magsafe end. This time around it took just a year and a half instead of 2 1/2 years which it did the first time around. What are folks here doing for this problem? Should I just suck it up and get a new one? Should I use some electrical tape (how long would that hold up?). Any ideas whether this problem is being caused because of the way I'm using the cable? It seems like it happens to several folks, but I was wondering if there are any tips for prevention.
