I don’t quite understand the criticism. It’s not gonna be top of the line, but it’s more than enough to replace my dying laptop from 2015 that I pretty much only ever use like a desktop anyway. And I can save myself the time and effort of picking parts, building, and dealing with shit not working as expected.
I think the main problem is since the steam machine is relatively open and, if it is sold at a loss, then companies will bulk buy them to replace their infrastructure. A bit like what happened to one of the PlayStation releases.
The playstation 3 sold like that because of the super powerful (compared to cost of equal pc at the time) cpu. The gabecube isn’t unique hardware wise, so even at cost, or slightly below, I couldn’t see this being a goto machine for infrastructure replacement. Many current sff devices already have more powerful cpu options available.
