I doubt this. Normal people don't care, especially not those looking in the used market. If this were not true, I'd not have a majority of anecdotal accounts of people paying asburd sums for baseline macs brand new that might have even already been out of date.

In one case, I knew someone who "wanted something to watch movies on" and bought a 13" brand new base model macbook pro through a third party installment company. Ended up paying around $4500 CAD for a 13" laptop with 4gb of ram. She tried selling it to me for a huge discount, but even that couldn't have been worth it.
