Re: What's the thing with "vintage" pickups?
Why use vintage pickups? Because they sound like this:
Listen from 5:38 to 5:47. This bit alone explains why seasoned players crave for "vintage" pickups.

Based in the 80's, but sounds timeless by any standard
We always tend to qualify as "natural" what we like but to my ears, this tone is clearly dated (I've not said "outdated").
Regarding the general reasons why players admire vintage PU's:
-culturally: there's the old myth of the "golden age" (= It was better before)... "Newer is better" is another myth, based on a belief in progress equally discussible.
-ethnologically: we, human beings, are gregarious. If a guitar hero uses a pickup, we tend to want the same pickup.
-technically: the metallic materials, insulation, magnets etc. used before the 70's weren't the same. they don't react to magnetism in the same way. This gives a distinctive tone that we recognize more and more while our tonal sensitivity matures.
-tonally: see my first answer above.
My 2 cents. No time to develop more: am too busy.
Signed: someone who uses vintage as well as modern speced pickups. Music is the goal to achieve whatever are the tools used, and not a pretext to develop controversies, IMHO.
