Interesting article. Still, I find it very to believe that Mac OS is faster than... anything on the same hardware system.
Maybe iTunes and other iApps are written better for the MacOS, but for us, Windows users, these are malware programs that you install willingly. They use 500% memory of regular applications, boot with the OS, and run even when turned off.
I could be wrong, but I always imagined Mac as lair for "legal" malware- software fighting each other for memory access and computer crippling itself to crawl before user even touched the mouse.
Maybe on Apple Mac, these same iApps use 80% regular memory need of the program in its class, and shuts down when not used, and doesnt start with the OS, but I really cant tell. Ifthat is the case on Mac, maybe Apple should try harder to do the same for us poor Windows users. If iCrapp suddenly started to be better than competition, I even might be inclined to try Hackingtosh, and maybe even get a regular Mac after that.
Not to mention that if iJobs got his ihead out of his irear, he might notice that OpenGL is horridly slow and also hacked for major pro visualizations apps to run better on “professional” cards like Quadro and FireGL. DirectX has been clean from such artificial intrusions from the start, and is now faster than OpenGL, even when the latter isn’t hacked by SpecCheatTests and other poor OpenGL-only programs... And lets not talk about games.. I don’t want to feel like a complete dick here.
