I agree with what people are saying that the console does look nice, what with it's engravings and all but, with the 3DS coming along, I doubt people will buy it (unless they are serious collectors, or something...
I, myself was thinking of getting one if I traded in my DS Lite for some money but I've gone against it as it is just an engraving. In the end, I just slapped a Tangela sticker that I've had lying around for oh.. 6 years onto the DS lid and it looks all the same. :)
