This doesn't mean that if I bought an equally priced (and benchmark-ed-ly faster) Windows machine that I'd be happier. I would basically just have a machine that is a little bit faster with an interface that I strongly do not prefer. Saving a couple bucks in this way would not make me happy.
These comparisons seem great for people that are truly apathetic to their interface, environment and workflow... the only people I know that fit that description are not playing Call of Duty.
I'm not saying that Mac is better than Windows. I'm saying my preference is a Mac, and with the perceived price-per-power that I normally feel with Macs, I feel like I got a great deal. It's quick, the battery lasts about twice as long as I'd ever need it to, and I'm happy with my purchase.
And at the end of the day, that is what matters.
