This is absolutely the truth. I've never been able to afford to own a 'real' console. The initial investment is more like a 'trap.' After you buy the console itself, it's a never-ending chain of more purchases. You need to buy more controllers and memory cards. You have to purchase each and every game you ever want to play. And in the past there was nothing else to do with the console if you weren't playing the games.
With a PC, the initial investment is larger, but then it's done and I never have to drop another cent on it if I don't want to. I have a large back-library of games that still work. I have free-games on the internet. I have game demo's galore. I can also use it for about a bazillion 'value-added' things that have nothing to do with gaming.
Having it be twice the initial investment is overcome in a matter of months, and I'll actively use my PC much longer than I'll actively use the console. (keyword 'actively').
Now, with the newer generations and the online capabilities, they are introducing things like Virtual Console, Indie games, game demos, other uses (ie Netflix), so they are getting to have at least a 'little' more value than they had before, but it still doesn't hold a candle to a simple PC.
