Apps for kids

Now that I've seen how kids enjoying using iPad, I have ultra strong incentive to write some free apps to let kids learn on iPad.  But suddenly I also aware that there needs to be some sort of parental control on the device so that parents can let kids playing with iPad along without worrying about them getting into trouble, like went off to some crazy web site, purchase apps without parent approval.

So parents, read these and see if you find iPad a safe enough education tool for your kids:
