When most of us think about Nintendo hardware, we think about the gimmick. The motion controls of the Wii, the second screen of the Nintendo DS, the stereoscopic visuals of the 3DS and the duality of the Nintendo Switch. These innovations define Nintendo's brand -- but it's not the only hallmark of Nintendo hardware.
The company is as much of a house of iteration as it is innovation, particularly when it comes to portable gaming. Almost every one of its handheld consoles -- from the original GameBoy to the Nintendo DS -- has been revised, retooled and released in a new form. Nintendo has made five versions of its original 3DS hardware, and it's about to release one more: The New Nintendo 2DS XL.
