First of all, having a cheap chair is a choice, just like having a choice to buy a cheap recliner. And while a 50inch screen might be good for your desperate need to express masculinity, the fact remains that it's just a huge magnifying glass magnifying a limited a amount of pixels. And as for carpel tunnel; I work in the IT for over 24 years, even was a programmer for over 7 years and have touched my first computer game in the late seventies and never developed any carpel tunnel, it's all about having a good understanding of ergonomics.
And lastly; people like me who have a job, don't have the time (or even the urge) to wait until the whole family goes to bed, to do what's basically nothing but playing a silly computer game. On top of that, I rather prefer to spend a good amount of money on a decent PC that can do more than just running games (work related, video editing, 3D modeling/rendering, image editing, developing music, etc), than to spend money on a limited console AND a limited PC that both combined would cost more than my current machine which is more powerful, not to mention that I actually make extra money online with my machine, while you're laying their in your flowered recliner with a six pack beside you.
