My hubby got this for his birthday and I know a lot of people probably would appreciate a review or two if looking for this for their families. We had a Wii for the longest time, which I did love but the Xbox has so many nifty features we actually put the Wii away since getting it!
This came with KINECT which is both amazing and creepy at the same time- it videos your actual body movements so there are no controllers to deal with- all controls are done with your own movement. This makes the sports and fitness games amazing!
We also use it for netflix now (our only TV subscription), and the format is so much better than the format on the wii. It gives a count down for loading shows (we live in the country our internet tends to be slower than when we lived in town), it lines up the next in a series automatically, when finished a series or movie it gives recommendations immediately.
Oh and EVERYTHING can be done with voice commands too!
