The fundamental premise of this rant is a simple one. I will spell it out once again. Analog circuits in consumer electronics should not make audible noise under normal operating conditions. Period, end of story. No negotiation, no qualifications. I find this premise so obvious that it seems absurd to even write it. Either Apple does not agree with this premise, or it is willingly shipping incompetently designed analog circuits. I find both possibilities troubling, but the first is terrifying.
I think the most surprising thing about the fact that much of Apple’s current hardware line-up suffers from noise problems is that Steve Jobs is famously fanatical about this computer noise.
