This is going to sound silly, but I kind of wish this was released along with the 3DS. I never use the 3D feature on the 3DS, with the exception of cutscenes in Ocarina of Time. That's it.
I actually like the design and the concept, and as a Nintendo handheld collector, I will be purchasing one! Not in the near future, but eventually, haha. The only problem I'm seeing is portability. Nintendo handhelds have been very travel friendly since the GBA SP because you could fold it and the screen wouldn't get scratched up, so correct me if I'm wrong, but I don't see a way to do that with the 2DS. It's a nice novelty though, and I'm very anal about my collecting, so yeah. Still getting one, even though it seems people aren't too fond of this thing. I think it's cute. :)
Edit: Even though kids won't be able to break this thing with hinges, I'm really worried about the screens, especially the bottom one. :x Kids are reckless. Both my brother and sister broke their DS hinges, and this thing is gonna get scratched up from the flo' up without a safe storage method. Though that's where carrying cases come in, I suppose. This thing won't fit in mine...and I have about four lmao. Oh well, new ones will be made.
