I know this isn't exactly what you asked for, but we have both iPads and Nabi 2's for the kids and end up using the Nabi most and they are WAAAAAY less expensive,
about $70.
Reasons...
You can
easily copy movies/music over to a micro SD card through either USB port or just taking the card out and plug it into your PC, and they play most formats.
Almost any game available for Android phones are also here for easy download through Google Play, including Minecraft Pocket Edition, and when you purchase it on your account, you can install it on both.
Durability, you can purchase (or sometimes comes with it) a rubber guard for them that make them virtually indestructible. Ours have bounced down stairs, been dropped in many parking lots and tile floors, you'd never know.
Has headphone jack.
Rechargeable batteries which last a decent amount of time.
Easy parental controls for downloading or purchasing apps.
Any of our car rides over 30 minutes always has them.
