i think if u put mac OSX in the position of windows it will get more vulnerabities than windows..
so many people trying to break windows because windows has to most users.. and more people is more familiar to it..

i wouldnt say windows is the most secure OS and OSX do not win the title either.. all OSes has its own flaws just waiting for people to exploit..

p/s.. i own macbook.. i use windoze.. and i love fedora core... all has their pro n cons.. not siding any OSes

CRAP or no CRAP.. it is still OSes... use at ur own will
