We puzzled over what to call this week's guest segment—the Dork Debate seemed too mean, so we went with Future of Technology Free-for-all. In fairness though, Popular Mechanics technology editor Alex George and CNET senior editor Dan Ackerman are neither dorks nor particularly pugnacious. They got along surprisingly well, often agreeing on the best ways to buy laptops, select phone plans, and play in virtual reality. Also on this episode, Peter Martin gets a too-late lesson from Roy in applying mortar to his bluestone patio (whoops), automotive editor Ezra Dyer tries out a jet ski that can go 70 mph, and we unearth a RIDICULOUSLY cool fact about parrotfish poop.
