its really attempting to post back, LOL
ok, Ive been using windows for 7 years, and linux for half a year, mac for 5 months so far. let me answer your question in a pc user's mind.
1. Steve Jobs called M$ copy machine, thats fine, I admit at the beginning of windows system, M$ did so, but now, its totally untrue, and people have old memory should face the reality today. sure, there is new featured in vista was in OSX for a long time, but on the other hand, a decent system restoration was in windows for 5 years, and apple now doing time machine stuff, even if i can't call apple copy, at least i can say, they are learning something from windows, can I?
2. PC user more demanding, like I said before, in their requirement and complaint about the OS in a deep, system structure level, not about how many new functions their OS will have, why? coz windows platform has plenty of 3rd party developers who can make small programs. they don;t need M$ to do it, in fact, if M$ did it, they sue M$, such as integrated IE/WMP/Anti-Virus softwares. PC users complaint about system's security (which I agree OSX is doing good enough already), not lack of a software that can do a "desktop search" or "dashboard" or whatever.
