Called the 2DS, this oddly designed system is shaped like a tablet--or, as others have pointed out elsewhere, a tombstone--and reportedly sports screens that are about the same size as the original 3DS. Oh, and as you may have surmised based on its name, those screens do not feature the same glasses-free 3D technology that's been the focal point of every previous piece of 3DS hardware.
Chiefly responsible for that reaction, I think, is what I consider to be the system's generic, Fisher Price-esque design. I'm also not a fan of the color schemes being offered to North American buyers (the white-and-red 2DS--see below--that will be sold in Europe is a bit better, but only a bit). Also, there's the name--which seems like a potentially disastrous idea given how consumers continue to be confused by the differences between the Wii U and Wii, let alone the DS and 3DS.
Those are just my opinions on the system, though; what are yours?
