I am very interested in the success of this device. I have, use, and love my Steam Deck, but my biggest hopes for this form factor in the future is it using generational CPU improvements to create a more diverse set of devices, rather than just chasing higher performance.
I don't actually play many games on my Deck that toe the line on its performance limits, I prefer to play 2D and lighter 3D games on it, while leaving the "spectacle" games for a more powerful system outputting to a much larger display at a higher resolution. I would love long-term to have a more smaller, lightweight device for portable PC gaming, and I hope that increased diversity in the market, running Linux-based systems (even if it's all just SteamOS) will help drive towards that. I think that the pipedreams of running x86 games on Linux on ARM on a really power-efficient device, even as unrealistic as they are, are far more likely to occur if there's a healthy market of Linux based systems, than they would on Windows handhelds given the state of Windows on ARM, and on these devices in general.
