The cheapest Mac laptop is $1,000. The cheapest Mac desktop is $600. So you are saying there are comparable PC's available for free and -400 dollars?
My historical stance on the matter has been that the money goes to R&D. I have no proof to validate my assertion, though.
And some quick links to compare. I could have taken more time on selecting the links, but this was pretty quick:

By consensus you mean misconception? I don't remember Macbook Air "clones" being cheaper by $1000. Some are even more expensive.
OTOH, I prefer to use computers, not specs. "Multitouch trackpad" may look the same in specs, but in practice it makes huge difference.8GB DDR3 1600Mhz RAM
Core i7 3.2Ghz Processor
nVidia 650M
256GB SSD

My mouse is usually a peripheral.
I would also imagine a clone to cost more than the original anyway, in many cases.
My Asus laptop costed 1000€ and beats the MacBook Pro 17" in the amount of juice I can extract from the hardware.
