The most obvious is to improve the 3D effect. Where you had to keep your head previously very quiet, now fits a face recognition to the effect of the head position. The effect itself is unchanged, including the occasional double vision and blurring on fast pans in the games.
Second major improvement is a second analog stick in the form of a small rubber Knubbels, reminiscent of the mouse replacement earlier IBM notebooks. He reacts relatively sensitively and works surprisingly well after a short time. With the four shoulder buttons (of which the two inner are pretty fiddly to use), can be operated without additional hardware finally complex games. Otherwise, the controls were a little back and forth pushed. Something stupid to use is now the Power button on the front.
The displays have remained the same in the resolution that acts in times of high-resolution display now sorely underdeveloped. But the contrast was somewhat improved by the image looks crisp. The processor performance was slightly increased, the load times partly remarkably shortened. The user interface responds by a little faster.
As magical money making Nintendo is again more on the purse of children, in the form of outrageously expensive Kunstoffblenden with which the console can be customized, and the Amiibos which unlock extras in some games.
One may wonder how long it still takes mobile gaming consoles in times more powerful mobile phones, especially when this hardware technology so much lagging behind as the 3DS. As long as Nintendo and third-party produce outstanding games, Nintendo has an ace up his sleeve. Anyone traveling Mario and Link wants, can not avoid the 3DS.
