Okay the screen difference is incredible.
Annoyingly I don't have a 220v > 100v step-down converter yet so I don't know how much charge this thing has.
Its such a better screen, EVERY game looks better. At first I was holding it as close to my face as I used to hold the old DS, and in some ways it made some games look worse. I mean, I can see blocky textures on Mario Kart that I didn't notice on Mario Kart before (although obviously I knew they were there). The videos on the Metroid demo and Castlevania show up artifacting more... its that much brighter...
but fuck, holding this thing at a healthy distance from your face, I notice all that a lot less and I'm just impressed by how crisp, sharp and bright it is.
Now to get that stepdown converter!
