Micro$haft will never be ahead, hopefully ever again. I'm hoping after Jobs dies Wozniak will return, he is the real genius.
XP/2000 (same core) are the only OS from MS worth using. Vista......7.......8 all bloatware (18GB!) and no more advanced than what a service pack would do.
Example- Win7 full screened apps are transparent causing massive waste of CPU/GPU resource if you have 8 apps "open". Dumb coding and design = post XP OS products all FAIL.
Can't comment on OSX.
