Valve is back in the hardware business as they have formally announced their Steam Deck handheld.

This seems to be the unholy lovechild of MSony consoles, the Nintendo Switch, and a penguin. Under the hood is a custom AMD Zen2 + RDNA2 APU, same as the PS5 and xXxBOxXx, though details such as core counts and clock speed have not yet been revealed. The device can be inserted into a dock (sold separately) to output to a TV, monitor, etc. It runs SteamOS 3.0, Valve's custom gaming-focused Linux distro, though there's nothing stopping you from installing Windows on it.
Let's hope the Steam Deck fares better than the Steam Machines.
