I enjoy my 3DS, it has many things upon it and has the Nintendo'E shop which is the largest "up" to possesing a 3DS.
Lol ive never had Anything like that so im sorry i can't help...
I personally think it's a waste. From what I've heard, there's no real advantage to choosing the 2DS over the 3DS besides price. The 2DS can't bend and can't do 3D. You can just turn the 3D off on the 3DS if you choose. That's just me, though. I don't know anyone that has one so I can't say anything based off experience. I just have a DSI (XL).
I just have a DS Lite, so I don't know. My brother has the 3DS and likes it a lot, though
