Agreed. Poll of 836 Americans? Give me a break.
Also note that in my experience, a surprising number of people think that "iPod" and "Mac" are company names, and may not immediately associate Apple with these products for some reason.
My experience too. I had an argument with a massively misinformed PC user about macs, and he seemed to think you pay royalties to "Mac" to program on them. I didn't even bother pointing out how "Mac" isn't a company, since he clearly was off his rocker... or should I say your average PC gamer.
