The Wii console, initially available in glossy white, measures a slim 8.5in long, 6in wide and 2in thick (157x215.4x45mm), and can be displayed either vertically or horizontally.
It is powered by a PowerPC central processing unit and a graphics processing unit that has been developed with ATI. It has 512MB of internal flash memory.
Nintendo Wii: 249 euros (£179)
PlayStation 3: 399 euros (£299) for the 40GB version
Xbox 360: 370 euros (£260) for the 120GB version, 270 euros (£200) for the Premium system (20 GB hard drive) and 200 euros (£160) for the Arcade system
The console has a built-in wi-fi capacity (or the internet can be accessed via a USB 2.0 LAN adaptor), and uses a system called WiiConnect24, which enables the system to communicate with the net even if the power is turned off, to receive updates or downloads.
Through wi-fi users can download "classic" games, surf the net and communicate with Nintendo's other console, the DS Lite, among other activities.
The Wii Remote, which resembles a TV remote control, allows users to play games through simple physical movements.
It can be used to jab like a sword, steer like driving a car, swoosh like a tennis racket. Nintendo hopes the change in gameplay will broaden the console's appeal.
The remote works through a three-axis accelerometer - a motion sensor - that can detect the angle it is being held at and how fast it is being used.
It connects wirelessly through Bluetooth to the console, via a sensor bar, up to a distance of 10m away. Up to four remotes can be used at any one time.
The remote also has a speaker, rumble feature and expansion port.
The Nunchuk can be connected with a cable to the remote control to allow two-handed play, to mimic activities such as boxing or using a sword and a shield. It also has a control stick.
Like the remote, it works through a three-axis accelerometer.
Classic controller: A classic non-remote controller (there is a special Wii design, or GameCube controllers can be used) can also be used with the Wii.
The sensor bar, which is connected via a cable to the back of the console, sits on top of or near a television set.
Through infra-red technology it communicates with the wireless controllers, sending the gameplay information back to the console.
