My experience is the opposite, no one ±5 years of me (born '90) ever had their own computer until they were in their late teens, and only a few had that then, most only got their own when they started working. Now my younger half-brother (born '12) and most of his friends have their own computer and consoles. And we're very much not higher-middle class, many (including my family) are working class and barely scrape by. It's just a more important thing for kids now so they save money for years and ask for all their presents to be money for it.
