TITAN:
It's just one option, hence the "STARTING PRICE" reference. That won't be with a Titan.
SteamOS and games:
That's going to be very limited, as only games written, or re-written for Linux will work. Hence about 98% of games will be Windows only.
Mouse/keyboard games:
The new Steam controller is an interesting solution, however many games won't work simply because the text or HUD elements will be too SMALL when viewed from a couch.
Benchmarking SteamOS vs Windows:
Only for games that exist on BOTH systems. Since we don't know what OPTIMIZATIONS were made when rewriting an older game like LFD2, most of the results will be useless.
Will the games even be 100% in terms of graphical features for a fair comparison?
DUAL-BOOT:
My big issue with SteamOS comes back to the Windows compatibility issue. I'm not getting a SteamOS machine that won't run my Windows games. Thus, I guess I'll be booting back and forth between SteamOS and Windows?
I like the POWER of a PC for gaming, but dealing with an expensive dual-boot environment to have full access to my Steam catalogue seems a big hassle to me.
STREAMING:
What I really want is a tiny Steambox that has TWO purposes:
a) Inexpensive, basic media box with simple gaming capability.
b) Streams games from my high-end gaming PC via an Ethernet connection with a low-latency Ethernet to HDMI chip inside the Steambox (and obviously wireless controller support to the Steambox).
*Mini Steambox for streaming, plus XBOX ONE and Steam Controller support please!!
