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.
While true overall, I was more going for the fact that people buy Ninendo because they want to buy Nintendo rather than because they want any random console. Meanwhile Sony and Microsoft are fighting for the same consumer - someone who wants an alternative to PC gaming. Which is also what Steam Machine is.
