I recently bought a Wii about 4 months ago and I will have to say its pretty cool.  Now the graphics are not as hot as the PS3 or the Xbox360, but the wiiremote allows for a more interactive game play in my opinion.  For xmas I ended buying myself the Guitar Hero III game by Activision and what can I say, I am addicted.  I recently beat easy mode the other day and now I am working my way through medium learning new tricks and to work through the tougher skill level.  My wife and I have a heck of a time playing this game together, so for all you married couples out there who like music and competition this is the game for you!  

 I came across this site recently and was floored, a nine year old is playing the dragon song on expert mode.... check it out!
