What the title says: it's a book. A book about Valve's Steam Deck. An
official release by Valve themselves, and full of pictures and
prototypes and information and the philosophy behind the device and...
look, it's a coffee-table book for a game console and ultimately, it's
just marketing fluff. But if you're interested in the device, it may
be worth a look.
It's freely available as a PDF here:

(Me, I'm waiting for the movie... or maybe, if I'm /really/ lucky:
Steam Deck: The Musical ;-)
