The Steam Deck changed quite considerably during the process of being developed and honed, as some freshly aired photos of prototypes make clear enough.
As PC Mag(opens in new tab) reports, Valve developer Pierre Loup Griffais posted pics of older prototype models of the Steam Deck – wheeled out for a press event over in Asia – on Twitter to show how the device evolved.
As part of the Asia launch press event, we made the design lab into a showroom of development history. My favorite are the playable prototypes: bootable Deck family tree from mid-2019 to now, from a couple of hand-built units onto gradual mass production. pic.twitter.com/TpU5I8D50pSeptember 12, 2022
As Griffais notes, these are prototypes from the middle of 2019 onwards, and it’s interesting to see how the design of the handheld gaming PC moved forwards.
Although the overall design remains roughly the same throughout, there are some key differences. The earlier models are notably more curved, with more pronounced contours at the side and front.
Also, the trackpads are circular in those older prototypes, and instead of a D-pad, there are four separate directional buttons top-left of the Deck. The thumbsticks on the earlier hardware are rather smaller, too.
Griffais further tweeted(opens in new tab) to clarify that the prototypes shown are “mostly” functional and boot up just fine, with a video provided to illustrate this, subsequently showing Half Life 2 being loaded.
It’s a rare treat to see the evolution of a device laid out like this, and the prototypes have certainly sparked some debate online, as you might imagine. Those earliest models look a bit clunky in some respects, and indeed retro, but it’s the middle incarnation which has drawn the most interest.
