The thing runs Windows so it's not a Steam Deck competitor... It's a has-been at launch.
Windows is absolute garbage for a handheld gaming device. When are these manufacturers going to learn and just ship the things with Linux? Many Chinese devices (made for running emulators) ship with some customized Linux so why aren't more mainstream manufacturers doing it? Seems like a no-brainer to make a better device and save money on licensing costs.
The answer to your question is in your comment. The reason is that those devices are designed to run emulators (usually nothing past gamecube/ps2 era). They run Android because Android has support for emulating software, but the chips used in those devices aren't designed to run current Gen games nor are they usually designed to run most Linux distros.
Although someone could try to do it, but if I had to guess it's more work to do it right (Valve made a custom OS for the steamdeck).
There's very little reason to buy this when Best Buy is selling the ROG Ally X for $200 cheaper with bigger battery, better performance, better screen, better support, etc... But will say I'm glad to see Ayaneo making it into Best Buy at all. Just... needed to be a year earlier.
This is a bad marketing photo because it takes way too long to realize it’s an image of a coastline or something. It looks like the reflection off a glossy and warped screen.
