Revolutionary controller design offers unique motion-sensitive gameplay options; built-in Wi-Fi delivers free online services and gameplay; Virtual Console has major nostalgia appeal; compatible with all GameCube games and controllers; built-in SD slot for storage and photo viewing; includes Wii Sports game; most affordable home game console.
Controller eats batteries and takes some time to get used to; online gaming and community features hobbled by horrible "friends code" system; nunchuk controller sold separately; lacks the advanced HD graphics and surround sound found on the Xbox 360 and the PS3; requires a wired receiver unit placed near the TV to interface with wireless controllers; can't play CDs or DVDs.
The bottom line:
It lacks the graphical prowess and rich media features of the Xbox 360 and the PS3, but the Nintendo Wii's combination of unique motion-sensitive controllers and emphasis on fun gameplay make the ultra-affordable console hard to resist.
