We all expected this because your favorite Steam games are not on the list.
This is why I am not using Linux Steam.
This is only the beginning... but I think a lot of developers would be encouraged to make/port games to Linux if SteamBox has success.
At the same time, people who only play on consoles may see SteamBox as a possibility for their gaming platform.
The cost is concerning, but those of us to already use Linux know that we can still play most of our favorite Steam games in Linux already.
If people shoot down SteamOS and just install Windows, then they might as well just build another Windows PC instead of gaining the freedom of Linux and games in PlayOnLinux.
I admit, I still use Windows for games, but as we continue testing our favorite games in PlayOnLinux (and having success) the doors are still wide-open for Linux to be a gaming platform.
All SteamOS needs is the developers attention...
The developers need the money's attention...
The gamers have the money but need their favorite games or new ones to replace them.
If Valve can keep SteamBox at $400 or lower then the price is right. Steam games are already cheaper than the console games.
They just need more HITS!
