Just like last year and the year before, Apple's kicking off its Black Friday sale in the land of Oz first. Australian Mac lovers can now buy the iMac, MacBook Pro and MacBook Air for A$121 less than their usual price, while the iPad and iPod touch dip down by A$51 apiece and the iPod nano is now A$25 cheaper. It's all for today only, but should also be followed by similar discounts in the US and Europe.
