I searched for this but came up empty- wasn't a thread on here about thisa a while back? I am considering buying my kids a system for Christmas. I know there are these 3. I am not interersted in DVD playing abilities, or playiong on line, or downloads. They are ages 8 and 4. I wouldn't play much, except with them. I don't know the difference between these 3, and I am not ointerested in 360 or PS3. Any advice or opinions? Thanks.
