"...don't need an Apple-enforce nanny state looking out for us. Look, it is not hard, at all, to make a Windows PC completely secure."
Uh, no, it is actually quite difficult for the average person (i.e. people with actual lives) to 'completely secure' a Windows machine. An entire generation of IT professionals owe quite a tidy living and debt of gratitude to MS for selling their swiss cheese of security products to the world. That 'they should just buckle down and become security geeks' meme is what Apple has shown to be a fraud.
The problem with the 'Windows is just a bigger target' argument is that MS faults are due to both neglect and intent. Security holes such as ActiveX are/were the result of predatory engineering (e.g. the intent of burying Netscape with a technology aimed at giving them a cheap, quick edge. A playground for malware? "Who cares.")
BTW Farhad, you can't have it both ways... either Apple is being a marvelously responsible by preventing 3rd party crapware from being loaded on the machine, or you think that being security conscious is 'a bug'.
Nevertheless, kudos for recognizing that Apple will likely deal with such security revelations quite responsibly.
