On this week's all-star episode, we present Bryan Chaffin, co-founder and co-publisher of The Mac Observer, who explains what Steampunk is all about. No hints! He'll also hold forth on the comments Facebook CEO Mark Zuckerberg made in response to Tim Cook's statements that, when it comes to Facebook and Google, you are the product, and you won't want to miss Bryan comments about the forthcoming Apple Watch.

You'll also hear from tech commentator and Macworld contributor Rob Griffiths, of Many Tricks, who will discuss his recent article, "The paranoid person's guide to a complete Mac backup." He'll outline multiple "levels" of backup strategies to meet your needs, and some of this advice, using Windows backup software, may also apply to PC users.
