From the article: "Issues with the way the new chip synchronizes timing causes dropouts and glitches in the audio stream. (It seems basically all USB 2.0 audio interfaces will be impacted. This of course unfortunately leads users to blame their interface manufacturer, but the fault lies with Apple.)" As someone who works with a lot of pro audio gear on the Mac, I can say that it's hard to describe what a show stopper this is. Glitches and dropouts are a catastrophic problem for almost anything involving sound, and they're right: If you're having those kinds of problems, you run immediately to the interface manufacturer. Still, I'm not sure many people using pro-grade audio interfaces (mine cost almost as much as the computer itself) are still using the USB 2.0 bus. Thunderbolt has been pretty enthusiastically embraced by the industry.
