The only reason anyone says "I am not replacing "X" just coming in as another addition" they are lieing and trying to make you not feel threatened.
It's a linux based OS. It can easily replace Windows depending on what you do.
Have you used it? It is LITERALLY big picture mode on a debian shell. The best you could do is install Debian with it, but besides that, it is literally like using the xbox OS.
Yeah... which is exactly why you can do anything.
It's very disappointing atm. It's just linux with steam installed. You can go on the web dl, skype, teamspeak, instantmessengers, and wine. And bam you have a fully function pc. I actually was hopeing for a more xbox like OS. Restricted. Oddly enough. But not at the same time. I wanted it to feel like steam. it doesn't.
Its only meant to be a home theatre OS. That was their intention.
It's meant to be a gaming OS actually. And intent is irrelevant with ability.
If OPENGL support was actually a thing. I'd use Ubuntu as my main OS.
