But you're right, it certainly seems that's the kind of game Cook is playing. Better than Windows, but no better, and keep the extra money.
To be fair to Apple, it does sound like this is a somewhat rare bug (only seen in high-load situations?). It's not as bad, I think, as ads in the OS. So, as you say, Apple just needs to be a little better than MS and that's good enough.
My Linux audio bug of the month is that output on all USB interfaces just stopped working. Not sure yet what changed (it wasn't an update, at least not immediately).
On WASAPI last I checked you still couldn't programmatically change the device settings from a user application, which leads to weird issues with sample rates and buffer sizes, which means ASIO is still necessary. Very sad.
I am now convinced it is the best audio stack on desktop.
