We don't have an operating pinnie in the house at the moment, but even in a partial state my daughter LOVES it!
She's not even 2 and a half yet but when you ask her what the best game in the world is she yells out PINBALL! A few days ago I asked her if she wanted to play pinball on the iPhone. She replie with "No Daddy, iCade!".
Bigger screen and buttons, can't argue with that logic!
