Handhelds are often sold on their 'pocket-friendly' nature, but the PocketStar is one of the few that can truly claim to slip effortlessly inside your pocket.
The PocketStar has recently passed its funding goal on Kickstarter, and costs 49€. It's packing an OLED screen and can play "original and exclusive" titles as well as emulators, which run Game Boy and Master System titles. The PocketStar also supports wireless multiplayer and will boast online leaderboards.
It gets better, though! Measuring just 50mm x 30mm x 10mm, the PocketStar is capable of running Doom, which is surely the benchmark by which all modern tech is judged.
The PocketStar is from the same team that successfully crowdfunded the Pocuter One, which raised 128.000€ last year. They even share the same hardware and platform; the PocketStar will have access to the Pocuter App Store, Pocuter API and Pocuter Cloud. That means that you'll be able to download games to the PocketStar using the App Store.
