Seven months later, Valve’s Steam Machines look dead in the water

So really the question is, are Valve making their money back? If yes, cool, they have free insurance. If not, that insurance is being paid for and obviously there's a cost/benefit analysis to be done. I don't think this piece answers that. It suggests they might have got something south of $750m, which seems high enough to be quite profitable. A better article would have cross-referenced this with any financial data on Valve that they could find, to see if they're actually losing money on these machines.
Valve isn't a public company so they're not obligated to provide any financial data, meaning that there's none available for deeper analysis.
I am hoping that the Vulkan API will be adopted by the games industry to act as a bridge between the two (Windows/Mac and Linux) performance-wise. Microsoft's plans to turn the PC into a glorified tablet or console walled garden is annoying enough. Now they're playing the same trick they pulled on XP users to "upgrade" to Vista, by releasing games that are "exclusive" to Windows 10 on their UWP (Universal Windows Platform). So far, it doesn't seem very consumer-friendly[1].
