No wired networking. This is a netbook device specifically designed for mobile use, so wi-fi, 3G and bluetooth should provide sufficient connectivity options. If you are looking for a desktop device, you might be interested in the Efika MX Smarttop which features an ethernet port.
As for audio, the Efika MX Smartbook has a combined line-out / mic-in connector (as opposed to separate input and output ports) in addition to a built-in microphone and speaker.
