this might be related to the topic. Which screen protector should I invest in gaf for the new 3ds xl?
I don't want scratches like my original 3ds on the top screen just from closing the 3ds =[
Please excuse the dusty 3ds =/
Go with Hori.
Also I just want to say that I am very keenly paranoid about the scratching situation, having had problems with it on past models as well.
I can confirm that the screens DO NOT TOUCH even when you slightly squeeze the system to simulate pressure that may be present in say a bookbag. Nintendo has done a better job at placing the rubber feet to prevent contact.
That said yes I installed a screen protector anyway
