A sarcasticgamer.com community blogger wrote this piece about why PC gaming will never die. Good read.
From the article: "PC gaming is like watching Mean Girls for the third time: you know its wrong, you know its going to cost you and yet you just keep coming back for more. Ever since Pong was released in 1972 gaming has grown from a weird past time to a popular medium. All the hardware used in consoles comes from technology developed for PC's and yet, strangely, PC gaming is dying.
Or is it?"
