When you're breaking out SSD speeds you're definitely getting into the "luxury" territory.
As I said in another comment:
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.
