I found some games for my 5yr. old daughter here

she plays with it when I need to keep her out of my hair and I havent had a problem with her wrecking it. sure she opens everything under the sun but heck it is easier to close a bunch of apps then have a 5yr old constantly rattling at you when your doing something like fixing a toilet or other home repair
