I love the Wii - I just got Netflix on it and it's so easy.
I love my Michael Jackson Experience dancing game - so much fun and such a good workout. "Just Dance 2" is fun too!
I really love the basic sports games that come with it. The bowling, tennis, baseball, etc... those are always fun and simple.
I also have Wii Fit which was great when I was using it every day
for exercise...
