Not sure. Could have sworn there was a prototype Razor tablet that never came to market which had removable side controllers as well.
My issue with a hybrid device like that though is the lack of power compared to standard consoles. I really want a decently specced Steam Machine that’s just a really good 1080p - 1440p gaming machine
Raytracing works pretty well for a decent amount of games at least on the Nvidia side. They just enabled RT by default for AMD GPUs but their RT is generally slower than Nvidia’s.
