I'm based in New Zealand, not the US. I see macs more among developers, but that's because I don't tend to hang around privileged rich kids that much these days, since I work for a living. When I was at university though, the vast majority of computer science students were running either Linux or Windows. I think on the balance of it, it was mostly Windows, but the Linux users seemed to get better grades and had a better idea of what they were doing. Macbooks were the computer of choice for the Arts and Commerce faculty students (most of whom, incidentally, did not have jobs).
