The G3 iBook appeared after I started this thread, I was repairing it for a friend. But that friend has now told me I can keep it. I've had a play with it, but tbh it is slower then my Pismo and the fact the logic boards are so unreliable just puts me off using it.

Took the plunge earlier today and bought a 2005, 1.33Ghz iBook. After reading several reviews and watching videos on YouTube, decided it will suit my needs. It's twice the speed of the Pismo, has a decent memory ceiling and Bluetooth.
