I bet they at least try to get rid of problems with the latest Lite waves. I've got a black one and it doesn't look as "iPodish" as the white one. Neither it has the hinge problem but these Scandinavian models might be from a newer production line anyway so the problem was fixed already with tightening the screws too much.
I deny it. I have checked two US blacks, they have the grid touch screen. Same with pink. on all 4 that i looked at (2 black, 1 pink, 1 white that was shipped shortly after the onyx/pink release) No yellow screens, but the white was neither yellow nor grid.
Its not that "white" ones crack, but a few defective ones did, it does not apply to all of them.
I had to replace my white DS with a new one when they first came out because of a broken mic. One thing I noticed different is they added rubber stopper pads on the top screen so it close's quieter and probably softens the close when its snapped shut.
sorry guys if this is off topic but as i just posted before i have a AUS DS lite and they cracks are starting to show ( cracked hinge and @ the back R button ) they are now still just little cracks but when they get bigger im going to try get a refund for a black one you think they would let me??
