Literally Gameboy's entire selling strategy was lateral thinking with existing tech. Gameboy had competition that had color and yet still won out by selling cheaper easier to develop for hardware with better smaller games.

Fuck home video game consoles that cost a thousand dollars and have teraflops of gigashits. I hope they never make another one. Make more Gameboys, god damn it. MAKE GAMEBOYS AGAIN. I want $200 handheld gaming devices for cute little cheap games that will nonetheless change your life.
