a great deal of these 'vulnerabilities' in OS X are from open source software projects which release the advisories.
i guess you haven't seen any security updates from Ubuntu/Redhat or any other UNIX, before have you?

Not only that, but it benefits for city folk are heavily debated, while the country folk will reap much of the rewards.

I lived in Sydney for 35 years before recently moving to London for contract work, and the last 6 years of that I had a 20 MB pipe, without the need for Telstra - the peddlers of an over the top expensive product.
The govt all the long wanted Telstra to stump up for NBN and when the pollies rubbished their proposal, it seemed like the smaller operators had a chance to collectively provide services at an equal rate.
Anyway guys, the NBN may come to your door, but in order to use it you'll have to shell out up to $450 and $750, and up to $3,000 to get a connection. Good luck with that.
