This doesn't sound like a traditional console, which is fine by me. I'm not interested in one console to rule them all, but all of Nintendo, Sony and Microsoft's various systems are really pushing it; I don't need another box in my entertainment center. As long as every game available on this Valve box is also on the big three's systems and/or PC then I couldn't care less what Valve does.
Hey, Sega fought valiantly. Why, I bet the Dreamcast was one bulky add-on away from whoopin' both Sony and Nintendo.

And I'm not just saying this because I was Sega kid.
To be fair, they didn't know the the PS2 would destroy them(and even Nintendo to an extent) and completely DOMINATE the console industry and hell gaming for the matter. The Dreamcast is their masterpiece. There was big hopes for it, and I was proud to have one, and the games I owned for it(SoA, Grandia II, DOA2, PROJECT FREAKING JUSTICE, PSO ver 1 and 2). I don't even know how in the world the Xbox survived against Sony. I guess they have Morrowind to thank for that.
I think there was a year that they fired their entire Sonic Team staff.
I used to be a SEGA kid, but I now have a deep rooted hatred for them and that doesn't entirely lie with their getting out of the console market. That's not to say that I want them to stay as they are. I would LOVE to see them "revive" and "redeem" themselves, but it's not going to happen.
