It's very hard to have this discussion without first talking about price/cost of platform choice. Early adopters are a small percentage of console sales over a platforms lifespan, when the consoles are at their most expensive. Most of the sales come when the console drops to around the $300 and under level. Where can you get a PC that can play the same variety of games that a console can for that price? Six months after you buy that PC, you're already probably thinking about upgrading certain aspects of your rig, which add considerable costs to the already steep entry level price. If the counter argument to that is higher game costs on consoles, and I'd argue that PS+ and Xbox Live have really turned things around the last few years on that front.
I've always found the conversation a little odd, seeing as how the PC "master race" loves their arrogant position atop their ivory towers. Price really does factor in a lot more than most people having these conversations tend to mention, and therefore it's hard to take them seriously.
