This is a FUD panic article. Trying to invoke the steam machine debacle to make the steamdeck fail is a poor tactic.
Confusion and inconsistency alongside varying prices and compatibility made the steam machines fail.
There is one* SteamDeck. Valve only advertises The Steam Deck.
We’re not getting an Asus deck or a Gigabyte deck. And I’ve heard people in the wild talk about the deck in a positive light. The Steam deck is never going to be like the steam machines.
*one in the sense that there is one model without drastic changes in design. Although the Glare-resistant screen is an outlier, most consoles have tiers of storage and even a pro/normal variant model.
