I guess I tried to address two issues in this. Let's put it this way: one man drives an Audi RS4, and the other has a Toyota Camry. Nobody argues that the man with the Audi has the better car, but one might infer that he also has more disposable income. That is why we assume people with Macbooks have more disposable income; they've purchased a luxury item when there is a commodity alternative. A backlit keyboard is definitely not required to use a laptop, no more than heated seats are necessary in a car. You think they're essential because you have enough disposable income that the utility of the money you'd use to buy the keyboard has become less than the utility of the keyboard. This is the notion of value. You can also, likely, afford to give a few dollars to a charity if you'd like.
Thats a fair comment but is a different discussion than the one this subthread is built on which is whether a mac is more expensive than a comparable pc. When discussing that then features like a backlit keyboard are important.
