Yes because thats why Apple's desktop market share is erm shall we say within the margin of error for measurement of windows users? In otherwords statistically insignificant.
But of course that is due to their OS been awful to develop for. Its very intresting how people like who've been at the kool aid are not programmers at all.
Apple made their Safari browser hardware accelerated, on erm windows. Turns out, thanks to the OS's excellent kernel design (VAX guys) and the HAL for the graphics subsystem with sterling work from AMD, nVidia and Intel with MS, have made it EASIER to write software on all of the combinations we see in the wild, than Apple have for there 2 different combos.
A nice example of why your view is bollocks.
