Jumping from a DS Lite the 2DS has been good to me ever since I opened the box. The insanely low price point and build quality is why I'd happily buy a second 2DS. Loss of 3D barely affects most games, while 3D is fun to toggle on and off as you see fit it's really not needed to enjoy the library of games available for the 3DS/2DS consoles.
If you're unsure about buying this due to the mindless disapproval from non-2ds owners (or experiencers) don't be. It's a fantastic product and one I am very happy with.
