My niece has the TAG and loves it. If you go to the Leapster website, you can also see the cards with facts on it. I bought her one about arctic animals and another but cannot remember which. She learned a lot from it. I am considering getting the TAG for my daughter next year.
I wish the TAG had been out when my older ones were little. They had the Leappad readers but I think the tag is more user friendly.
