Is 1990's equipment vintage?

Yeah, no worries about the motive to interact! Just musing out loud about your question -- what might the label imply or be connected to in our various ways of thinking. I suppose I proposed a couple and I’m interested to see what other people post (of substance). (Some people just interject to see their words in print, I suppose.)

I think by definition it is vintage, but many think of vintage as 70's or older...we don't want to realize how much time has gone by and how old we are...

Vintage is 1970's or older. Unless digital. Then last week or older.

But 1970's was vintage in the year 2000.  It's 2020.  Shouldn't we move the bar?

Ok, 1970 was 30 years from 2000, you have a benchmark of 30+ years. So, 1990's would just becoming vintage assuming you want to measure in years. Webster says "a period of origin or manufacture",
