What also has changed: no I2S connector for audio chips any more, and I had hoped for a proper 3-lane I2S to be able to do 5.1 HQ audio without relying on either the crappy USB bus itself or cheap quality USB interfaces.<p>Not to mention that I2S sound is far less workload on the CPU than USB sound.<p>Oh, and why doesn&#x27;t the Wifi&#x2F;BT antenna have an SMA connector for external antennas, e.g. directional antennas?!
