tbh if you know your way around one 3ds you know your way around them all......i could probably do everything i really need without knowing what it says, but i just figured i would pay the extra and know its just the same as if i owned a UK model
.....plus there is the whole JPN consoles shipping with 8.x, so if nintendo release 9.3 and block gateway before you receive the console, you will have to wait until a game is released with 9.0-9.2 onboard, and you would also need to import a japanese game to update.....which would probably end up costing you the difference if not more than just paying the extra to get a EU console
