Want to see what could have been? Valve developer Pierre-Loup Griffais has revealed some working prototype units and they look pretty interesting.
Writing on Twitter, Griffais mentioned "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."
Here's the pictures:
Must admit, the one with white corners does look pretty sweet. Fun to see the iteration they did on the design here but I think overall we got the best of it in the released model.
In a follow-up post, Griffais mentioned "The best part is that they (mostly) all still boot, serving as an exciting reminder of how far things have come since.
This one has a Picasso APU, at about half of the GPU power of the final Deck. The flatter ergo was an interesting experiment and taught us a ton about comfort."
That post also came with a short video to show one of the older devices working:
On top of that, the official OnDeck Twitter account has also been showing off a massive Steam Deck for the Tokyo Games Show and it looks pretty fun.
