"their security model has been working well so far" -- that is to say, the Mac security model, which has hardly been tested at all (relative to say, Windows), has been working well -- which isn't saying much.
That may be, but it's been a blissful 10+ years. :)
Ribbing aside, the OS X security model is, generally speaking, the Unix security model, which has been around a lot longer than Windows. Henry Spencer is attributed with saying "Those who do not understand UNIX are condemned to reinvent it -- badly." Perhaps OS X has done it badly, but perhaps not as badly as others.
I agree that lack of security problems is not indicative of good security, but Apple does seem to be making good decisions. As I said earlier, they've got some super smart security people working for them and letting them drive the security model.
