Selvom der synes at være stor uklarhed om hvad Steam Machines er for en størrelse, er formatet ikke noget Microsofts Marc Whitten ser som en direkte konkurrent. Det fortæller han i et interview med Engadget, hvor han blandt andet siger:
"I personally don't know how to think about Steam Machines yet... I'm not knocking it or whatever. I continue to think that PC gaming -- the sort of uber configuration and I can change everything and I can mod -- that's an important thing and there's a lot of people that wanna do that."
"When you get into that living room environment, you don't want to spend any of your brain cells doing anything but being entertained. I don't want to work on it; I don't want to feel like I have to know how it works. I would like to be blowing things up now, or watching a thing now. That's the fundamental thing that you want to do... I think there's space for both. I'm not sweating it."
Hverken Steam Machines eller Xbox One har fået en udgivelsesdato herhjemme endnu, og indtil det sker, er det således svært selv at bedømme hvorvidt der er noget bag Whittens argumenter.
