My refurbed DS Lite (had an original with a hinge crack and traded it in) has a tad pinkish look to the bottom screen. It's not horribly bad, but it is noticeable. It doesn't distract from the games though and it still looks way better then the original DS's screens so I've really no complaints. I figure with the DS, I'm likely to get a newer version if one comes out anyway. It's just such a great little system to have and I've got something like 48 games for it. So I'm not too concerned.
On a side note, I have Pneumonia right now... last night when I was getting a perscription filled for antibiotics at Shoppers Drug mart, I noticed Nintendo has a really nice display of games at Shoppers. I was pretty surprised, If I wasn't so sick I would have been tempted to buy a game. They had both DS and Wii stuff. I wonder if they get any Wii's into their stores? They had a nice selection of DS's...
