Just three words: awesome awesome awesome.
And for those asking for it, here are my slides, in which I try to explain the new "glitch-free" audio scheduling core of PulseAudio that I recently commited to the glitch-free branch in PA SVN. I also try to make clear why this functionality is practically a *MUST* for all people who want to have low-latency audio, minimal power consumption and maximum drop-out safety for their audio playback. And thus, why all those fancy embedded Linux devices should adopt it better sooner than later. The slides might appear a bit terse if you don't have that awesome guy they usually come with presenting them to you.
