I'm not a big fan of Gabe Newell, and I really don't personally like the idea of having only a digital vs hard copy of the games I own, but Valve overall as a company certainly has been one of the biggest entities (if not THE biggest) keeping PC gaming alive and well, and for that they have my respect.
That said, this talk of Steam Box, if it happens, could turn out to be more (or should I say less) than a way to make Steam's PC versions of games play easier with HT gear. God forbid they should go whole hog into the console world the way the once respected by PC players Epic Games did.
All things change in time, some for the better, some for the worse.
