Their interest isn't necessarily in squeezing out the most margin on each unit. If unexpected market conditions let them more or less hit their original margin targets but get far more units installed in homes, that could be much better for them in the long term.
There's a lot we can't know as outsiders, at the moment.
i agree. Valve's money machine is with the steam platform, rather than any hardware sales - breaking even on hardware is sufficient imho.
Valve's existential threat is from microsoft closing off windows somehow (or extracting rent...like a store!). Therefore, pushing steam machines which can be run without windows, is both business expansion as well as an insurance policy.
Being pragmatic, I wonder if Valve benefit from the health of the PC market, whether they'll also put efforts into helping people get more life out of their existing machines, or individuals/businesses refurbishing to sell on the used market with more confidence. There's already an angle for reducing e-waste with the win10 end of life if it can be tied into installing linux.
Wasn't that true with the previous incarnation of the steam machine, the valve index, steam controller, etc.? IIRC their VR gear was some of the most expensive consumer level gear on the market.
