Considering the 3D isn't really necessary for most of the games, and it gives a lot of people a headache, I think the 2DS is actually a smart move. The problem is that it makes Nintendo look a little silly after betting on the 3D thing.
My 3DS is a 2DS I just don't have the 3D on, plus the added bonus of it being a flip you can protect the screen from damage while it's not in use even if you don't have a case for it, they could of just added a firmware update to be able to disable 3D in the options so a small child does not turn it on with the slide
The 3DS games are good, mostly aimed at the younger players though so not much for me there (there are a few games though, Resident Evil Revelations & Metal Gear Solid 3 remake are a couple of them), the DS set of games that are already there are great though and have a nice mix of games, that cover most gamers needs
Design wise I don't like the look of the newer 2DS or see the point really unless a lot of 3DS consoles have been getting the top screen snapped off or something, so went with a flat design instead of a flip top, as I stated on the first line they should of made the 3D as an option maybe even a passworded option along with age settings ect to make it child friendly rather than just removing the 3D
I can't call this a new console though it is still a 3DS with a poor design
well at least, 3DS had a mouthful games available in market (specially rpg, jrpg to be exact), I always bring it to my work as my stress reliever. But I had my 3D option off since it drain the battery faster and it makes you dizzy like having a motion sickness.
while my Vita sits in my desk for a while and sometimes play DJMax Technika Tune on it. For now, it doesnt do much at all, specially that Vita game updates had only games that is recycled from PS3 game library, most of them are indie games in PS3.
