In response to your edit: if you define "specs" broadly enough to include the comfort and the color of buttons, then sure, "specs are all that matters", tautologically.
On the other hand, with this broad of a definition, no, there is no other computer on the market with the same "specs" as a Macbook Pro.
If you really think marketing is the only reason someone could prefer a more expensive but lower horsepower car, then this conversation is a waste of time.
“Why would anyone ever buy a BMW, when you can get a Dodge Challenger with more horsepower for cheaper?”
