I've been trying to get a refund from Nintendo since yesterday on my XL. I've seen other units and while some of them have the yellow screen issue in a lighter way it's still pissing me off. It's made me mad enough to the point of also willing to break it like tpax

(well not really, but I am pretty mad)
It's just sloppy screen manufacturing by Sharp, period. I'd rather wait till they have good batches than put up with it. I don't want to spread FUD, but if you are anal about screens like me, it can be really irritating...
