Valve unveils the Steam Deck, a Linux-based PC gaming handheld to challenge the Nintendo Switch

Valve is best known for its Steam PC gaming store and for classic gaming franchises including Half-Life, Portal and Team Fortress. However, it has ventured into hardware with its failed Steam Machine venture which was aimed at trying to bring a consistent hardware and software experience to PC gaming in a similar style to consoles. Undeterred, it seems, Valve is back for a second crack at gaming hardware in the form of the new Steam Deck.
