Many PDAs are becoming increasingly travel-friendly, so now frequent fliers now can rely on their personal digital assistants for more than just scheduling meetings and making calls.

With the Blackberry or the Palm Treo, you can now access Orbitz mobile service.

This lets you check hotel vacancies in 20 U.S. cities for the same night and call the hotel to confirm your reservation by just pushing one button.

If you type in the three-letter airport code into your PDA’s FlightStats application, you can find out how long the airport’s security line will be, based on data from the TSA.

Some PDAs can activate GPS tracking, which can give you turn-by-turn directions to get where you need to go.

Other features on these PDAs will help you translate a language, check the weather, find restaurants and even find places to dance—that is, if you have any energy left after all that.
