Here’s another thoughtful piece by John Gruber, this time on computer security exploits and the conventional wisdom surrounding them.

But is it wisdom?

I don’t think anyone would dispute that Windows?s overwhelming market share is a significant factor as to why Windows is also the target of an overwhelming majority of security exploits. The question I?m interested in – and wrote about in “Broken Windows” – is whether this also explains why security exploits against Mac OS X are practically non-existent.

All of this comes as Apple addresses serious allegations that it is not open enough regarding security issues. All in all a very interesting pair of articles.
