More than 55 million homes have at least one iPhone, iPad, iPod or Mac computer, according to CNBC's All-America Economic survey.
Of the homes currently untouched by Apple products, one in ten said that they plan to purchase a device in the next year.
Possibly most remarkable, though, was that Apple is suffering none of the 'brand saturation' of other products, as Americans are not content with owning just one device.
The research indicated that US homes owning an Apple device, on average have three of them, and almost a quarter intend to buy at least one more in the next year.
"It's a fantastic business model - the more of our products you own, the more likely you are to buy more," said Jay Campbell, a vice president of Hart Research Associates, which conducted the CNBC survey.
"Planned obsolescence has always been a part of the technology industries sales model, but Apple has taken it to a whole new level."
The research also indicated that Apple buyers in the US tend to be male, college-educated and younger. Home owners and high earners were more likely to have more Apple products, it found.
Only 28% of people earning less than $30,000 a year owned at least one Apple product, compared to 77% of those making more than $75,000.
The survey found that the desirability of Apple products cuts across political allegiances, as around half of right-wing Republican and left-leaning Democrat supporters owned a device.
However, that gap may widen as 26% of Democrats intend to purchase an Apple gadget in the next 12 months, compared to just 19% of Republicans.
Since Apple released the latest model of the iPad earlier this month, the high resolution tablet is understood to have sold around 10m devices around the world.
