As a former travel guidebook author, I am biased in favor of old-school print travel guidebooks. Not that I am completely averse to digital travel literature; I use e-book guides too. But print guides are easier to highlight and annotate, and never run out of battery, need a wifi connection, or require an expensive international data plan to access. This little video from DK Eyewitness Travel books celebrates the many virtues of old-school travel guides.
