The E6 is a relatively new retro gaming handheld built with the task of emulating up to Sony PlayStation Portable games. Available for under $50, the E6 gaming handheld resembles the Valve Steam Deck, albeit on a much smaller scale.https://www.notebookcheck.net/Steam-Deck-mini-lookalike-shown-emulating-Sony-PSP-games-with-hall-effect-joysticks-for-under-50.806470.0.html
Doesn't look like a steam deck at all. It looks like pretty much every other handheld though.
I'm sorry but this does not resemble a 'Steam Deck' at all.
It is just another horizontal 'retro rig' making use of the RK3326 (in which there are nearly COUNTLESS examples/variations).
Sadly lacking the CPU/GPU power or even Wifi to be a viable Streaming client, personally IDK why the endless stream of these devices are making their way to market.
