I want a dedicated handheld where the physical design is part of the full gaming experience.
For example, the dual screens of Donkey Kong Game & Watch, or the left and right buttons on Ball and Vermin, which are functional parts of the gameplay itself.

The device’s form and controls are designed specifically around that one game, rather than being a generic handheld running software.
Ideally,
I want something pocketable, with excellent battery life and one or two simple, endlessly replayable action games that I can pick up and play instantly.
