Nope. Steam Machines (Or any PC-trying-to-be-a-console machine) will never be mainstream.

People buy consoles because they're simpler than PCs. They're basically just plug-and-play and you don't have to hassle with graphics settings or drivers and whatnot.

People buy PCs because they offer more customization. You can choose your hardware, choose whether you want pretty graphics or high framerates, use almost any controller you want, install mods, and run other software.

With a Steam Machine, you get none of those benefits the consoles or PCs have. They are still restricted like a console, but have the complexity of a PC (How many different types of Steam Machines are there? They would've had a better chance of success if there was just 1).

i don't think so

Not after the huge blunder of today. The ModGate is killing their PR.

And honestly, I can't blame the modders. If I worked 10 hours, and someone wanted to pay me for 2 I would be rather pissed. 3 and 5 go to Valve and Bethesda.)

hardly anybody is excited for these machines, more options leads to confusion

"John Woodward, regional manager, Northern Europe and South Africa, Zotac: We see console gamers moving over to the PC platform as they get more seriously into their gaming – demanding better graphics performance or taking a competitive edge in eSports."

Yes, because all us gamers are into gaming mostly for the graphics and think only people in eSports are real serious gamers........

Considering we had hundred threads about games/exclusives graphics I would say many do.   Even checking thread titles sometimes say enough 
'Sucker punch will have jaw dropping graphics'

Some do. They are usually the loudest ones as well

A third party box without Fifa cannot be successful in Europe.

Not to mention that it isn't making PC gaming accesible enough (you still have to look at specs) or price.

If they had figured out a way to port over windows/DX games, maaaaaybe (and that would be a miracle in both technical and legal ways).

since that's not the case, chances are -10% (as in less than zero).

No.

more expensive, less games.... just no.

a linux gameing pc.... to beat a real consol? I bet perf/$ is in favor of the real consols too.
