I have a black new 3ds xl
My 3dsxl is the usual pink color but I ordered a decal for the inside to be pink also.
-snip-
I've had the plain pink 3DS since Christmas 2012. The cover on the circle pad is loose, but apart from that, it's perfectly fine.
I wish I had some stickers/decals/whatever they're called for it, though. I remember my first DS Lite getting an AC:WW one, then a few years later getting ones with Paper Peach on them. But that DS broke six years ago...
lol I'm still playing on the original first gen 3ds. I will be picking up my ACNL 3ds with the faceplates at the midnight release at my gamestop ^_^ I'm so excited!
