Pros
Pro Native graphics processor support
The OS natively supports Nvidia, Intel, and AMD graphics processors.
Pro Streaming service integration (under development)
Valve is in talks with streaming companies such as Spotify and Netflix to bring their features to SteamOS.
Pro For entertainment, it just works
What media center software do for videos, it does for games (and later videos).
Pro Seamless setup
The first time LinHES is launched, you are prompted by the configuration tool which is built using the same toolkit as MythTV itself. This allows for a seamless setup experience since LinHES automatically detects and configures the necessary settings correctly. This means that things like recording hardware, infrared receivers and remote controls are all configured automatically.
Pro Great functionality out of the box
LinHES comes with a suite of programs already preconfigured to make it function as a media-centric appliance. Stuff like NFS and Samba are included for sharing files, Webmin and VNC provide remote administration capabilities, furthermore there are various remote system monitoring tools and packages for supporting file-transfer methods (one of them is Bittorrent).
Cons
Con Hard to install
If you've installed Arch you're probably fine, but for those used to simple installs like (Ubuntu to name just one) you should prepare some patience, determination, and painkillers. Good news is, it's getting better (it's very young).
Con Not built around the desktop experience
SteamOS is, first and foremost, meant to act as a gaming console - it doesn't ship with even some of the most basic applications, such as a file manager or image viewer. As a result, using SteamOS as your primary operating system would require a fair bit of work.
Con Support only for 64-bit Intel architecture
The latest releases of LinHES only have support for 64-bit Intel architectures. While it's not worth it to worry about 32-bit Intel systems it's worth noting that the absence of an ARM release is problematic.
