If you are a serious gamer, you play both.. but if you're a really serious gamer, you play on the PC. Most offspring of the PC Master Race only habit consoles for the good exclusives (see: Red Dead Redemption).
Stuff gets made on PC. This is how we get things like "Minecraft", etc. The PC also acts as "the nexus". You're attached to a universe while you sit in front of it, it's unhealthy and intoxicating, but it is what it is. Console gaming is more of a novelty, and you're discouraged from communicating, being creative, or constructive. It's a one-way form of media.. it's like cable TV, people talk to you.. that's it. This forces the entire medium to be derivative of itself, relying on outside media to support it; see:Xbox Live.
PC *is* the hub, it can't be derivative. However, gaming on PC can be forced into being derivative and wholly shitty if its thematically 'console' and lacks the tools and inspiration of the "Three C's" mentioned above.
(Also, that time when I have to enter any amount of words into a console with a gamepad. Credit Card information, address, game key and DLC keys. I feel like an alien trying to interact with a primitive society, it's very annoying and a bit quaint, but the end-goal is for a good purpose.)
