Nintendo Game Boy Advance/SP

In March of 2001, Nintendo released the Game Boy Advance, formerly known as Project: Atlantis. This was Nintendo's successor to the Game Boy and Game Boy Color lines, sporting an ARM7 SoC which had a hybrid 16 and 32-bit architecture. Its display was similar to the previous Game Boy Color, lacking a backlight, but increased resolution. Along with having its own vast library of games, the Game Boy Advance lineup (excluding the Micro) are backward compatible with both Game Boy and Gameboy Color titles with the Gameboy Color's Sharp SM83 SoC on board to support the feature. The Game Boy Advance also had many accessories including but not limited to: The e-Reader, an add-on that allowed for the scanning of magnetic card stripes to unlock game features or load up old school NES games, as well as the Wireless Adapter, a way to play games across multiple Game Boy Advance consoles without need for cables.

Two years later, in 2003, the Nintendo Game Boy Advance SP was unveiled. This fixed a lot of the original's short comings as well as a chance to give it a fresh face-lift. It was now more pocketable with its "clamshell" design where the screen was separated by a hinge that could close shut when not in use, shrinking the footprint significantly. This upgrade would also give it a now rechargeable battery as apposed to the AA battery compartments on its predecessors, and arguably the most notable update, the addition of a lit screen. The original SP referred to as "AGS-001" had a somewhat dim front lit screen, with the later "AGS-101" having a full backlit display and is typically the more sought after of the two.
