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.
No, I mean that I can buy a PC that beats the top of line Mac products with double the RAM, a newer GPU with more video RAM, better processor, costing 1000€ less.
My Asus laptop costed 1000€ and beats the MacBook Pro 17" in the amount of juice I can extract from the hardware.
