As the title says, vote for your favorite 80s/90s hand held console.
For some this is an easy question and for others maybe not so much.
My first true hand held console was the Atari Lynx II. A great system by all means, but i preferred the Sega Game Gear, both for the looks of the console and especially because for me personally i much preferred the games on the Game Gear.
I also prefer the Game Gear, especially when I played most of the games on my A1200 with AmiMasterGear
I am not a big fan of Missile Command, Robotron, Pac Man and other old arcade games. Much prefare stuff like Sonic, Castle of Illusion and Wonder Boy.
The Game Boy was also brilliant with its huge library of games and long battery life.
The GameBoy was okay, but no match for the nicest games of the Game Gear.
Now imagine if there was a hand held Amiga 500 
The Atari Lynx can be considered as a hand held Amiga. It was developed by some Amiga engineers with collaboration of Epyx and Atari. Too bad the technology back then wasn't up to making hand held A500.
