I used one up until GBA came out. I was never much of a portable gamer before that, as all I really played were Link's Awakening, the Dragon Quest I+II port, and all the mis-named Final Fantasy games. I remember going on a year-end school trip in 2001 or so and bringing it along. I got made fun of while my friends were playing Advanced Wars. = \
I do, my very first gameboy, got it shortly before the newer GB came out. The images on it now are really faded too. In fact I just played a year and a half ago. When all my friends got new DSs me and another friend went old school on them with our oldies.
I have one. It's my sister's though. I was way too young when they actually came out. I did get a Gameboy Colour when my brother got one though, and I have that too. Then, I got a Gameboy Advance. Then recently, I got a special Edition Minish Cap SP, and a year later a DS. And now, a few months ago I got a black DS Lite... oh, and about a year ago I got a Micro. Waste of Money.
