I have a white DS Lite which I bought in 2007 so I could play Pearl. It's still in very good shape, and I have at least one of the original styluses that came with it. I don't plan on getting another console until the slim model of the 3DS comes out in a few years. After a while, accessories will stop being made for the original anyway just like stores no longer sell new DSPhat accessories.
Bright Blue DSi! Got it for my 13th birthday from my parents. I love it!
I used to have a pink DS lite, but I decided to give it to my best friend for her birthday, who's little sister promptly broke it in half for no reason whatsoever. :c
I have a DS Phat (still in great condition minus a few major scratches on the outside). I have a DS lite but the top screen is coming off so I don't use it. I currently use a DSi... though, I wish I wait for the XL's release.
I still have the original Nintendo DS, I've had it since the year it came out. xD It's still kickin', and for some reason when I got it I scratched out the bar code under it with a pen. =S I've been thinking about putting at least one sticker to decorate it, but so far it still remains undecorated.
