I think if valve had gone the route of swappable SoCs, it could have done better since you could choose to upgrade it in the future for relatively cheap and not get locked in to the platform. They didn't because they wanted to release a ubiquitous product that devs could target as a hardware spec like the steam deck.
1k for essentially gaming laptop performance is gonna be a tough ask in this tire fire market. The biggest savior by far has been users boosting their old platforms to the max because everything current gen is hella expensive.
Plus it will be undercut by PS5 which is the biggest contender. Valve's major edge is the software, but a $400-$500 premium is not worthwhile for many.
I also think they underestimated 4k users. There's not that many 4k users in the PC space because its expensive, but a lot of people have 4k TVs because the display tech at that scale is pretty cheap. People will want 4k output if they're gonna use this as intended with a larger screen.
