There you are in a strange town, like Chicago - or Brno. How do you get around? There's always a taxi, of course. But public transportation is not only cheaper, it often gives you a much better sense of the city and its people. Armed with Métro, you'll always be prepared to get around a new city.

Métro is an amazing accomplishment, a free guide to public transport systems - subway, bus, tram, elevated, suburban systems, ferries, etc, etc--in some 400 cities worldwide. It runs on your PDA (Palm or PocketPC) or your Smartphone and is updated frequently so you can always keep track of station closings and construction annoyances.

The Palm version, which I've been using for years, provides station searches, a station list for each line, hours of operation, places of interest and tourism info, color coding, a contacts list keyed to the proper station for each, and even a choice of routes (fastest or fewest connections).
