Well, what it basically comes down to is this:when designing a proprietary closed source OS it makes more sense to use your own filesystem rather than an open source one, so Apple,Microsoft,and many others have created their own, some are better than others.Now, on the otherhand, some OS's that are open source will have to be able to deal with the other filesystems and formats or they will have a tough time being useful as they are so rare as OS's go.So linux for example, can mount and read or write to about 60 different filesystems at present, some are really good,some arent.It also makes it easy to pick some good ones, and right now, the journaling ones are the filesystems of choice.The original system popular in linux was ext2, it works, its fairly good at dealing with fragments, but it could be better, the ones that came later are much much better.Windows isnt as modular or standardized like other OS's so changing filesystems is a major undertaking, matter of fact the defrag program in windows didnt even work properly till windows XP came out.Windows has made the decision to focus on other things, the consumers havent done anything about it, so here we are.The standard way of "fixing" windows is a format and reinstall, that is unheard of in other OS's believe it or not,so is defragging, neither linux nor OS X need defragging.
