Just brougt my 700mHz iBook in today to get the logic board replaced for the seond time in 8 months. From what I can see over at the Apple forums this is an extremely common problem. I love Apple's innovation but their methods of managing DEFECTIVE products sucks. I have a feeling that I will just be bringing my iBook in every 4 months for the next 2 1/2 years for it's 4 month logic board replacement. It's under Applecare but the problem is they are just replacing one defective board for another. Hell, even if they send me an entirely new machine IT WON'T HELP THE PROBLEM. Although the bill would about $385 every time I get a new logic board so this problem has definately given me my moneys worth as far as Applecare goes. I bet Apple only does something when they realize they are spending more money on replacing logic boards than they make on Applecare. Like all big companies it's all about the bottom line! I know most other computer companies aren't any better but, to be honest, I've owned Dells and Toshibas and never has any problems. However, even with my iBook's problems, I do have to say that I love my iBook, when it works!!!!!
