I think many know but just dont mention it often. I know ive been told this by a lot of moms and parents i know including my sister who both her, her hubby and their 6yr old girl all have an ipad.
KIDS!!!! Its the perfect toy for kids to play with! Whether its games, movies, their kids shows in the car, educational needs, reading. You name it.
And thats why i guess apple went with a 10.9" LCD screen size. Cause anything smaller and it would be too smaller for most kids.
