Are you or have you ever had problems with your Mac charger falling apart?

I ask this question because after 2 years I developed a small slit in my MacBook Pro charger. I didn't put any electrical tape on it and my cord got worse. Now, most of the wire is exposed and is fraying. As much as I didn't want to pay $80 bucks for a new cord, I didn't want to buy a knockoff due to battery malfunctioning, but I think this issue has already affected my battery. I looked online and there are [b]many[/b] people with a similar issue. It's believed to be a design flaw. I'm thinking if there are enough people who are experiencing this problem, then we all can bombard Apple as a whole and have the material of the cord to be made with a stronger, more durable material. Personally, Apple is beginning to irk me. Their "top of the line" brand" is laughable now. I've never had an issue with the cord of my PC cords tearing and disintegrating.
