Glad your iBook is back in action. My iBook is the only "new" (this century) Apple laptop that I have sentimental attachment too. All my other later Powerbook/MacBook(Pro) notebooks have come, and gone. The iBook bridged me back to Apple machines from Windows based machines for video editing, to MOS9, and then to OSX.
It, and my (upgraded to the max) QS2002 are the only 21C Macs that I intend keeping, all the others are just appliances.
