Linux and Android are the future of handheld gaming
Devices like the Steam Deck, Ayaneo 2, and even the Nintendo Switch have taken the world by storm in recent years. Portable handheld consoles open up a new world of experience. While Nintendo has been making handhelds for years, the first two offer PC gaming on the go, complete with good performance, excellent battery life, and the ability to do so much more with the software.
However, the Steam Deck has a leg-up over the Ayaneo 2 in one big department: the operating system. It's so much easier to do whatever you want on SteamOS, a fork of Arch Linux, not to mention the reduced overhead. On the one hand, this decreases the cost since there's no need to shell out for a software license for its distribution. However, there are disadvantages to using Linux, such as the requirement for the Proton compatibility layer to ensure that games built for Windows are still playable.
