You know, the only part of this approval for is probably the SteamOS which is Debian based and that is that as well as the Intel Core i3 processors for Intel CPUs which combined are for secure gaming purposes I have come up with. But even then, I don't play so much of Steam games as admitted as the first few games I played on that service before were obviously the indie games on Steam. I don't know what were the interesting games to find on Steam which are not the Indie games back then.
The first problem that makes things backfire about Steam Machines and SteamOS is the fact that they have the dual-boot feature and the connection between Steam Machines and PCs for network gaming. The network gaming like that may be fine but the dual-boot feature is by then a no-no that may cause SteamOS to be IGNORED. This may make you think of the Steam Machines as another kind of gaming PCs and speaking of gaming PCs, they may be extremely expensive and speaking of expensive, the range of prices are from $499 to $6000+.
Your best bet will be to stick back to playing Steam games on Windows or Mac client or have better secure gaming with the Wii U and Playstation 4 as this approach from Valve to me is going to backfire if done incorrectly.
