lol wut? And a PC game wouldn't look better on a larger screen? Especially considering PC games have significantly higher resolutions?
And you just listed a negative against PC gaming...generally being confined to a desk instead of relaxing on the couch or a recliner. And if you do that, guess what? Hey, you can use that 46" HDTV as a computer monitor! Hence, including the cost of a "nice HDTV" as part of the total console cost is ridiculous.
I can buy an XBOX 360, a PS3 and a ~32 inch 1080p HDTV for $1000 and it will play games just fine while looking pretty decent at the same time. I could build an okay gaming PC for $1000 with a cheap 22" monitor that will be able to play most (but not all) games at medium settings that are barely any better than the settings a 360/PS3 runs at. If you want to run newer games at better than console settings, you will need to upgrade the video card.
Your argument is poor and does not stand up to scrutiny. PC gaming is a horrible value if you are looking at bang for the buck. PC gaming is no longer "superior" to console gaming. Sorry.
