The point isn't that the MacBook Air isn't better by some metrics than PC laptops. A Rolls-Royce is "better" by certain metrics than a Toyota, too. What makes a device luxury is if it costs substantially more than competing products that the average person would consider a valid replacement.

But what is that, exactly? If you look at all aspects of a laptop: CPU, RAM, SSD, battery life, screen quality, build quality, touchpad, OS, and put them in order of importance for the average consumer, what would be on top? I don't think it's the tech specs.
For instance, I would be willing to bet that for a large number of consumers, battery life is far more important than the tech specs, which means that a valid replacement for their MacBook must have equivalent battery life. You also have to consider things like the expected lifespan of the laptop and its resale value to properly compare their costs. It's not simple.
