The Steam Deck marked its third anniversary on Tuesday, a milestone met alongside reports that estimate Valve has shipped over 3.7 units as of the end of 2024, accounting for 48% of all handheld gaming PC hardware sold that year.
While that's still a fraction of what Nintendo managed to achieve with the Switch — and potentially an even smaller fraction of what it hopes to achieve with the Switch 2 — the Steam Deck has become one of the more important devices of the modern era, an incredible achievement for a product exclusively sold through Steam, with no presence on digital or brick-and-mortar store shelves.
