I'll always remember how I got my black DS lite back in 2006. I wished for one for christmas, and on christmas day, my father gave me Mario Kart DS. I thought "Yeah! I'll get a DS!", but as time passed on that day, I lost my hope and got mad at my father since he got me a game but no system to play it on. After I ran up to my room in anger, my father came in, smirking, and handed me a small, wooden casket. In it was a black DS lite, waiting to be played with. I was so angry and happy at the same time.
Needless to say, that DS lite has a special place in my heart, and even though it's far from fully operational now, I still own it.
I've had since upgraded to a DSi in 2009 (which was the first console I got on launch day) and, after that one broke down, to a 3DS at launch in 2011. In late 2012, I upgraded to the 3DS XL and have since sold my original 3DS for another DS lite, since that one has the GBA slot and no regional lockout (praise the lord for that).
Even though there'll be next to no games for this system anymore, I still discover "new" DS games frequently. I've probably bought more DS games than PS3 games this year. And there's still so much more I want to get, but I only have so much money.
