I don't know if price is always the deciding factor in the PC vs console argument. There are other things to consider. A run down:
1. A gaming PC always cost more in both time and money, at least, initially.
I can go to the nearest store buy a console and a game, come home, hook it up, and be playing in less than thirty minutes, with a total cost of around $350. I can do the same thing in an hour with a PC, but it'll cost me over $800. Of course that's a pre-built computer. If I want to build it, I have to learn what parts I want, find them, get them shipped to me, put it together, buy the game, and finally I can start playing, with a price tag of around $600.
2. Learning the PC code
To use a console I only need to know where the on button is, and when buying a game make sure it's made for my console of choice. For a PC, I need to know my specs vs the games specs, what parts and who they are made by, if they're compatible, how to put it together, how to take it apart, and an entire list of terminology I would not use otherwise. See, if you work or live in the detailed computerized world, this is simply tools of the trade, but if you are only a casual computer user ( and most people are) this requires a rather large amount knowledge to be learned, and while learning it would no doubt come in handy in other areas of life, it seems a bit much for simply wanting to play a game.
3. Comfort
I think most people would agree that they play video games to relax. A console is made to be played sitting on the couch. It's designed so that it fits in the compartments of most entertainment centers, with controllers that will reach to the couch, and don't require a level surface to use. A PC is designed to be used at a desk or table. Which means an office chair, albiet a potentially really nice office chair. But, even the nicest chair has difficulty competing with the couch in terms of comfort. In short, the console is more user friendly for the gaming purpose.
I am not saying the PC is inferior. In my opinion, it has several benefits over the console, however, it also has an equal amount of disadvantages.
In the end, it seems that if you are only looking for a game to play, the console is the easiest, fastest, and most comfortable way to play, while the PC is the most advanced, detailed, and potentially ( long term) cheapest to use.
Arguments about the positives and negatives of each medium, usually don't address all the issues ( including my post, which is not in-depth) and often involve a futile attempt to point out why one medium is supposedly better than the other, or at the very least equal in all catagories. Which is not true.
