I just wanted to get some feedback from those experiencing this issue. My iBook is going out on Teus for it's 3rd logicboard since January. I thought that when the extension progam was announced Apple would have developed a permanent fix to this problem, but apparenty this is not the case. After reviewing my proof of repair from the last two times the same part # is listed as being replaced. Would it be worth it to call and complain and try to get upgraded to a new model? I think I've read a few cases where this has happened. It just really sucks when I use it as my main computer and all that data is never safe, if my logic board is going to go out every few months. To add to the problem, Apple Care no longer offers data protection. So if they decide to wipe your hard drive or replace it, you are screwed.
