I remember when I bought a New 3DS model, I had to transfer all of my data off of my old 3DS, and wasn't able to maintain two devices at once. Has this been remedied with the Switch?
I will probably be buying a second Switch for my family this year, and I was hoping this would be a good place to ask how the family account works and if I will be able to download my titles and sign in to both Switch units with the same NNID.
