Kids learning games?

We have the hand held Leapster and my kids love it. My 3 year old and 5 year old really enjoy it. They have many cartridges with cool cartoons the kids like such as Dora, Spongebob and Clifford. The cartridges have many spelling. math and fun games to play. It has been dropped many times,taken everywhere and it still works. We have had it for 3 or 4 years now. I would highly recommend it!
