If it was a decent pc for a decent price, maybe. Even though I'd much rather be a hardcore PC gamer, I just can't justify paying 800 dollars or more for a PC when the 400 dollars I spent on a ps3 has served me perfectly fine for a generation's worth of gaming.
Put it this way, if they can spec it in such a way where it's just as good as a ps4, and the same price I would jump at it. The problem with PC gaming is that optimization varies much more compared to consoles, which is why I don't think that feat is possible.
Also, if they could line up publisher partnerships to get on board with steam OS (meaning all/most games come to that platform this gen), that would be a big bonus!
Don't know enough about it to make an informed opinion either way. Specs? Will we be able to upgrade it, if so, how much freedom will we have? Price? Etc.
The whole reveal was pretty useless in my opinion. We all knew that there would be a steam box (steam machine...), but this didn't really say anything more than what we already knew...and that they'll start a beta.
Edit: And Steam OS has yet to convince me. Right now, only a tiny fraction of games come out on Linux. Valve say that they've got deals lined up, but will that be enough? There's a reason why Linux gaming has never caught on with the mainstream (mainly that Linux is still too complicated for most people, and the lack of games), and I'm not convinced even Valve can solve this.
We know next to nothing. So there's nothing to consider really.
"Hey wanna buy this... gaming hardware I have?"
"Price? What specs does it have? Features?"
"Yeah sure! That sounds good. I'll take it."
Okay, think of it this way: If the conditions are optimal, does the notion of Valve-branded living-room hardware appeal to you?
Not really useful for me, seems great for the console crowd though.
It's really not, which is what leaves me scratching my head. I'm the sort of person who would love more affordable entries into PC gaming, but it's just not where I'm prioritizing my cash right now. This really doesn't do anything for me, as a person who would identify as a console gamer. It doesn't seem to do much for anyone with an already capable PC, either. So I'm sort of at a loss.
I'm planning on partitioning my laptop's hard drive and putting SteamOS on part of it just to see what all the fuss is about and, hopefully, to stream games from my PC to that laptop so I can play anywhere in my house.
I won't be buying a pre-built box for it, though.
