Let's see... when I was growing up, my older siblings and I would fight over the NES we've had since... 1986, I suppose. We wouldn't literally fight over it, but anyway...
In terms of consoles that I personally owned, my first portable system was "the big gray brick," also known as the original Game Boy, and between Christmas 1994 and now, I've acquired over 28 games for it. My brother also had a Game Boy, but after the screen cracked on mine about five years ago, he said I could have his, as he is no longer an on-the-go gamer. For home consoles, my first was a silver GameCube that came with one controller, Wind Waker and Ocarina of Time + Master Quest, among other games.
More recently, I've acquired a red and black DS Lite, my brother's PS2 slim, several Super NES's, five PS1's, a model 2 Genesis, three other NES's, and a large suitcase packed with controllers. After reading that last bit, it would be safe for you to conclude that I'm a serious collector. :D
