Get back to me when you find the same question in Apple's knowledge base, or asked on a Linux or BSD forum.
This isn't a punditry game, it's just fact. Someone who made a conscious decision to not run a mainstream OS is generally going to be a bit more intelligent, or at the very least more educated. Someone who took the time to try 5 different Linux distributions, or pay a bit extra for a Mac (pre mini era, anyway) put some thought into how he/she uses their computer, and isn't going to ask "where is the any key?"
HP/Comaq does sell non-windows machines, but I think you'd be fooling yourselves to think its UNIX/VMS audience is who this is directed to.
BTW, IQ is a horrible measure of intelligence.
