That's exactly what I was getting at. If consoles are the same price point as a PC, you might as well just buy a PC which has less limitations with how you use it.
My argument was that as a casual consumer, it doesn't seem like a good deal to spend more than $300 on a console. Since the current Wii U released at $299.99, it's more than just possible for consoles to be released at that price point. If a console was $500 today, I would spend a bit more to buy a new PC and stick to that. At least when there doesn't appear to be any exclusive games that look like must own titles. Consoles aren't even just for playing games anymore, they're like media players for streaming video. Any PC can do that too. Just reading up on the "benefits" of this Xbox One console, it includes a built-in Skype client for videoconferencing, the ability to use voice commands and gestures to navigate the console's user interface, cloud computing, the ability to automatically record and share video highlights from gameplay, and support for live streaming gameplay online. How many of these things would help improve the way games play? It just sounds like upgrades for a new computer. I'm not going to buy a new console at $500 just so I can use voice commands to boot up a game, or so I can Skype with people, or upload gameplay videos to youtube or other video sites. I can already do that with my PC, not that I bother with that either. Also, when we personally buy new computers they tend to be used regularly for about 10 years before they're too old to be useable for daily use. Consoles are usually replaced every 5 years or so, it's just not worth spending so much on them.
There was a time when consoles were actually more suitable for games than PCs, back when Super Mario Bros came out side scrolling games of that quality weren't possible on home computers, it wasn't for a few years until Commander Keen pulled it off on the PC. Those days are long gone, computers are just as capable as consoles for playing games.
I was also a bit confused by the article that you posted, I assume you posted it to support your argument but the article actually supports my view.
