Once the nerdy niche player, Apple is now officially mainstream: the majority of American households own at least one device from Cupertino, according to a CNBC survey of gadget ownership.

The survey found that the typical Apple owner still tends to be male, college-educated, younger and lives on the West Coast. (CNBC collected no personality data so other fanboy stereotypes cannot be confirmed.)

But 51 per cent of American households now have some kind of Apple device, and 61 percent of households with children own Apple devices, compared to 48 percent of homes without kids. So Apple's market-share looks assured for the next generation.

The other great news for the Foxconn rebrander, is that people who have Apple gadgets tend to want more Apple gadgets: the average number of Cupertino products per Apple-owning house is three. Out of the households that didn't own any Apple products, 1 in 10 planned to rectify that within the next year.

CNBC polled 836 Americans by landline and cellphone in March.

In other news, a Nielsen poll shows that the iPhone has made huge gains in the smartphone market, pulling market share from Blackberry and Nokia and now owns 32 per cent of the smartphone market. Android has 48 per cent and RIM has 12 per cent.

Judging on sales from the past month, Apple is doing even better with 43 per cent of smartphone sales in February 2012 being iPhones. ®
