We still have an old PSP that we kept for our kids to play with. My son is 6 years old and has been playing on it for the last year. He loves it. It is still very old school, but for him it is perfect. Will probably upgrade when he is a bit older.
This is a funny one. Whenever there is a decision to be made in our household and no one agrees we usually play rock, paper, scissors to make a decision.
