I honestly treat mine like it's a million dollar bill. I wipe it off with a cloth every time I'm done using it, (not when I put it in my pocket though) and I don't even let my little brother play it, because his hands could be dirty. If I drop it, I have to make sure nothing is scratched up, or broken. I use the circle pad very carefully, I don't ever use it in DS games, or DSiWare. I use the DPAD. I don't move it around like I do with my GCN controllers. I could care less if those break. They're only $7... and I have 6 of them. -.- I know, I sound a little paranoid about keeping my 3DS safe from harm. XD I want to know how you treat your 3DS? Do you just throw it around, and hope it works later, or are you like me?
