This is simply not true. I started on a Crosley. While it might not be cool, I'm not ashamed of it. I needed something cheap to see if this was something I was really interested in or if it was just a passing fancy. It's like buying someone a point-and-shoot to see if they're interested in photography. No, it's not an SLR, but it's a toe in the water and they can get into more serious (and more expensive) stuff if the interest persists.
The great thing about the vinyl boom is that you can do this now, too. They've got records in Barnes & Noble (my grandma bought me a record from there for Christmas because she knows how much I love records. I didn't have the heart to tell her I've already got the White Album. it's the thought that counts). They sell them at Urban Outfitters, at Half Price Books, and even at some Targets.
They might not be the standard, but they can be what stores call "selective sales," (at least that's what BP called it when I worked at one of their gas stations). Where I worked, they were things like promotion-only candy bars and gum. It's basically something a person didn't walk into your store meaning to buy, but once they see it they decide to anyway.
So, vinyl music's role has changed, but many people buy it for the same reasons, I suspect. Is vinyl as big now as it was in the 80s? Nope. But it's growing and people are interested in it again. It may not be the dominant medium, but it's getting people interested in their music and in the related ephemera (artwork, mechanics, etc). I'm glad, because for a long time when I didn't have a turntable or records, I wanted one. I had fond memories of them. Now, they're back and I can share that affection with others, including my 9-month old niece when she's old enough (though I bought her a Fisher-Price turntable music box for Christmas this year and she giggled and laughed at it for most of the day). The more things change, the more they stay the same. The only thing that's really new in the vinyl resurgence is that now people have a choice in mediums and they're choosing vinyl anyway. That's pretty cool.
