I agree w PP, our 5yo DD has had an iPod touch for the last 3 yrs, she loves it!! Wouldn't touch a leapster. They can def grow w a child, apps are cheap (99 cents) or free and u can get used iPod very cheaply to start.
She has books and music on there, games and shows she watches and apps to help learn to write. She loves the camera, so cute lol.
There are also potty training apps and teeth brushing apps that are extremely fun and helpful w the kids.
I also believe since she has alotta vision issues that it has really helped her hand eye coordination. It's amazing how fast she picked it up. If I could go back Ida never spent a penny in anything else.
Be kind whenever possible. It is always possible.
