On this week's all-star episode, we present tech journalist Jim Dalrymple, Editor in Chief of The Loop, who will discuss the status of the various mobile platforms, what Google has to fear from Samsung, and why he has problems relying on Google services. From Laptop magazine, Reviews Editor Michael Prospero covers some of the best and worst tech gear tested in 2012 and so far in 2013, along with whether lacking five features that are on the Samsung Galaxy S4 makes the iPhone 5 "ancient." Commentator Kirk McElhearn, Macworld's "iTunes Guy," and the editor of Mac OS X Hints, makes a special return appearance to talk about Apple's answer to virtual desktops in OS X, known as Spaces.
