The Globe and Mail points out that some tourists are now using their cellphones as tour guides:

"Move over dusty ol' guidebook, there's a new kid in town: the cellphone. Our beloved gadgets are now leading us through zoos, and allowing celebrities such as Steven Tyler and Sigourney Weaver to show us around Boston and New York."

Audio guides for the cellphone are available for $5.95 at TalkingStreet.com, which offers the option of Sigourney Weaver narrating a tour of Lower Manhattan and the World Trade Center site and Jerry Stiller providing audio commentary for a tour of the Lower East Side.

The creator of Talking Street, Miles Kronby, explains the appeal of using the cellphone as a tour guide: "Our interest is to make these tours as rich as possible, with other voices, not just dry readings from a guide book into a phone. We're aiming for something well beyond that. Something vivid and interactive, to make you feel like you're in the middle of it all."
