I agree with the Leapster recommendation. The kids can take it with them, which can be great in the car. There are games for a range of children. My son is 5, and he got his for Christmas when he was 3. He goes through phases where he won't play with it as much, but then he will get it out again and play with it nonstop. Out of all the toys he has gotten, it is probably one of the things he has gotten the most use out of. Oh yeah, he left it in the rain one time, and it still works!
