It looks like they've finally addressed the long standing audio latency issue in Android. I was watching the Android Fireside Chat and they mentioned that audio latency on the Galaxy Nexus, running on Jelly bean, has been reduced from 100ms to 12ms. But, they're still not satisfied as they want to reduce it to below 10ms. So it looks like some of those iOS music apps which are heavily reliant on low audio latency targets may finally be coming to Android.
