That's aside anyway, just consider there are several Linux architectures. When we write code we should consider those other architectures .. Non-x86 Linux is used pretty frequently. Dare I say that x86 and x86_64 installations combined don't out weigh all the other architecture installations, that's only a guess but I wouldn't be surprised if that's true.
