Phoronix posted a review on the Valve Steam Deck
A quote from the article:
Over the past nearly 18 years of running Phoronix, I have come across many interesting Linux-based products from Linux embedded in motherboards for instant-on use to the BlackDog USB port pen drive Linux servers to solar-powered super-computers in trash cans. The most fun and promising Linux-powered gaming device for the masses though is launching today: Valve's Steam Deck. I've been fortunate to be testing out this Arch Linux derived handheld game console the past month and it has been working out very well -- both as a portable Steam gaming device but making it even more compelling from the Linux enthusiast angle is its "developer mode" that effectively turns it into a general Linux handheld and also being free to load your own Linux distribution of choice.Valve Steam Deck Review
