quote: Kinect is awesome, maybe the next version of it will be completely lag free and higher resolution.
quote: It does not even come with a proprietary connection, its USB so that older xbox 360's could use it.
quote: Because the Kinect sensor's motorized tilt mechanism requires more power than the Xbox 360's USB ports can supply, the device makes use of a proprietary connector combining USB communication with additional power. Redesigned Xbox 360 S models include a special AUX port for accommodating the connector, while older models require a special power supply cable (included with the sensor) that splits the connection into separate USB and power connections; power is supplied from the mains by way of an AC adapter.
