I'd say Macs have a far greater association with developers and tech nerds now, most code was being written for Windows and Unix back then. I was in a Computer Science University program in the 90's, and our labs were full of Unix workstations, things like SGI and Sun. When the iMac dropped, they put them in the non-CS labs. On a personal level, I've always felt the relatively current Mac==developer trend is driven in large part by fashion, but I've never been a fan of the Apple/Mac ecosystem even though I can respect what the Mac is on an engineering level. So maybe I'm biased.
