When the DSi LL launched, Nintendo president Satoru Iwata pointed out that the portable's larger 4.2" LCD screens meant that it was easier to watch others play.
"Nintendo DSi XL realizes beautiful game screens even for those who look at them from an angle," Iwata said earlier. "You do not have to peek closely into the monitor of another player's video game to get a good view anymore. Nintendo DSi XL is going to offer a new play style, where those who are surrounding the game player can also join in one way or the other to the gameplay. When you look at the home console video games, you can understand that the fun of great games can be conveyed to and shared by those who are watching the player play."
