Hi: I have read about the problems of the iBook G3 issues and I just had to chime in. I can understand the anxiety of the owners of the iBook and wondering whether or not their iBook is next. I have shipped my 900mHz iBook to Apple when I felt it was running hot. The Apple Computer Support people said it was fine. I got the extended warranty as well. So far so good. It was put together in April or May 2003. I still am using my 700mHz iBook which was rebuilt and is running quite well. For some reason, I have chosen to use it more often. Though, I am not sure when it was manufactured. Since it has been rebuilt last year, I'm not sure whether that makes a difference. What I'd like to know is whether or not I could find out when my 700mHz iBook was actually manufactured. Any advice in this matter would be greatly appreciated David
