My incredibly generous (shopaholic) wife gave me a Wii for valentines day. I wasn't expecting it as I had only intimated that I would like one in september for my birthday.

The Wii is different from 'normal' consoles because the controllers offer a much more natural experience. You can literally place a controller in the hands of someone who has never played a computer game in their life and after 30 seconds of instruction, sit back and watch them play Wii Sports Tennis. The Wii seriously broadens the audience of people that will enjoy using a console and allows three generations of a familly to enjoy the gaming experience together. If you don't believe me try discussing the merits of Halo on the Xbox with your Grandma then ask her to have a go at Wii tennis and see which she enjoys the most.
In essence then the Wii is all about fun and doesn't take itself too seriously it is the volkswagen beetle of the console world and I think Nintendo have struck gold with it.
