The Best Travel Gadgets of 2009

Growing tired of tunes while you travel? Yearning for a bit more intellectual stimulation on the metro? iMinds offers eight-minute audio books across 12 categories, ranging from the Cold War to the history of bank notes (for when you can't sleep, perhaps). Think of them as audible Wikipedia entries accessible on the fly. Most devices in our Best Travel Gadgets arsenal can serve as MP3 players, so there's no need to pick up a separate device for tracks from iMinds.

iMinds: $0.99 per track
