Two flats which few people speak:
_ The stylus end is 2x more smaller (keep aside your original 3DS stylus for greater comfort)
_ The separately sold AC adapter!
BUT CAUTION:
I had an exchange on the first New3ds I bought: no Micro SD card was detected by the console. Opening the capos, I've realized that it was not fully inserted into the port, and that she herself ejected as soon as I réinsérais! I do not know if this is a recurring problem, but remember to check that this concern was not an isolated case !!!
