I just recieved a new iBook from apple because my previus iBook had so many problems that they replaced it. Anyways, After using it for 3 days, the cd-rom drive has suddenly sstopped working. Whenever i put a cd in it sounds like it is scraping around. Everyone i know that has an iBook has sent theirs in to be reapired at lest three times. Does anyone experience these much problems or have we just had a lot of lemons?
