I can't resist adding my 2 cents. I have repaired, upgraded and given away a total of 4 iBooks -- 3 3G and 1 4G. None of them showed signs of the video chip issue. I've thought a lot about it because it seems I should have run across it by now. It occurs to me that how the machine is used could contribute to the chip separating. All these cases have a certain about of flex because they are plastic -- or titanium surrounded by a plastic frame. The logic board is mounted to an internal aluminum frame that is attached to the case. If the machines are generally used on desktops or tabletops, very little stress is transmitted to the logic board. If the machines are often used on laps, cushions or other soft surfaces just enough stress may be transmitted to the board to pop the chip. I understand the solder can also simply get old and fail. I just haven't seen an instance of it yet. All the machines that that have gone through my hands, the 4 ibooks and 2 G4 Powerbooks, are still humming along without a problem. I'm not ready to endorse the idea that the problem is inevitable.
