RIM's Ryan Biden, GDGT's Peter Rojas, Ford CEO Alan Mulally, lots of tablets, Shredder test-drive

Welcome to the latest episode of the The Engadget Show, in which we change things up just a little bit. Everything starts with a trip to the New Mexico desert for a ride on the Shredder, love child of a tank and a skateboard. Next, Tim and Associate Editor Jacob Schulman sit down with RIM's Ryan Biden to talk about the BlackBerry PlayBook. Then, Tim has a chat with Ford President and CEO Alan Mulally about the future of transportation, and just what'll be driving you in to work in 20 years. After that, Engadget founder Peter Rojas joins Tim and Managing Editor Darren Murph to look at a plethora of tablets. Favorites are chosen, lines are drawn, and allegiances pledged. There's also talk of Amazon's next play in the tablet space, the death of Flip, and what's up next for GDGT.
