Many thanks for the pointer toward MacTracker. I checked there also and, sure enough, the model Eric has DOES NOT have an audio input socket. Neither do any of the other QuickSilver models, nor the Digital Audio model. Like you, I cannot explain Apple's logic with this situation. It does seem over-strange to delete audio input ability on those models in particular and not on other/later models. Do you think that customer feedback might have brought back the audio input socket? Maybe next year we will start getting QuickSilver models for recycling, but in the mean time, I have a couple pallets of high-end slot-loading iMacs and about half a pallet of earlier G4s than Eric's waiting for me to attack next week. The program I volunteer with refurbishes computers donated by various California government agencies and places them in school classrooms at as low a price as possible.
