Wii

The Nintendo Wii features an IBM PowerPC "Broadway" CPU at 729 MHz and an ATI "Hollywood" GPU at 243 MHz, with 88 MB of total system memory. It comes with 512 MB of internal flash memory for storage, supports connectivity via built-in WiFi (802.11b/g), and uses slot-loading optical drives for Wii and GameCube discs. The system's key innovation is its motion-sensing Wii Remote controller, which uses Bluetooth technology and an infrared camera to interact with a sensor bar.
