I have a 32Mb VRAM early 2002 (April) Dual USB iBook that the LVDS cable went about ten days ago. (Less than nine months old). Came back from warranty repair (after three days!) and now it's going back again, this time with screen flickering when dimmed and an appalling woodpecker sound through the speakers (not hard-drive clicking) from boot time.
I think Apple do a "Fight Club" on their dodgy gear balancing the cost of repair of the bad ones against modifying the production line or actually admitting the problem and doing some kind of recall or trade-in deal. Guess who loses!
I think it is legitimate to be concerned!
As for knowing for sure, until the G4 iBooks have been out for about nine months we won't know, unfortunately. At least the white dots on the 15" display showed up quickly!
Spoke to a guy in Apple Tech Support today and he cautiously advised (conversations recorded and all that) to buy either a 12" or 17" Powerbook. That is, he was really saying don't touch the 15"!!!!!
