I prefer BC just because I don't like having 100 consoles in front of my TV.
I have my Nintendo Console. Microsoft Console, Sony Console, Receiver, Media Center PC (X51).
Soon I will have a OUYA on it. It's UNLIKELY but if Steam Box offers something special compared to my X51 I'll get it as well.
It just seems ridiculous to have two Sony consoles when one could of did everything. Though I'll be forced to if they don't offer a BC option.
If you tell me to "use different TV's" that's where I keep my old game stations. (I'm a bit of a extremest and hardcore gamer)
I have "generational" gaming sections. That way the old stuff is on what they looked best on (such as 480p flat CRT's or for the exceptionally old scan lines) --- WARNING: http://www.gamefaqs.com/boards/user.php?=2426382 Is a very well known Troll, please do not fall for their shenanigans!
