More than just for email, your Blackberry, Palm Treo, or any other PDA is useful for other things, including getting yourself the scoop on how long is the airport’s security line.

Life is even easier with a PDA to guide you. Here are some of the services available with your PDA:

Hotel Room. Even if it’s the last minute, you can get a list of available hotel rooms with your PDA. Orbitz, a hotel mobile service, lists about vacancies in 20 US cities. Although the service can’t help you get booked, it provides a phone number however, which you can readily access by pressing one button in your PDA. Take heed though, because Orbitz charge a bit more for calling the hotel, rather than directly contacting the hotel yourself.

Airport Scene. FlightStats will help you scope what’s happening in your airport, including letting you know how long the line is in airport security, flight schedules, and delays. The data imported to your PDA comes from the Transportation Security Administration so it’s reliable. Just type the three-letter code of the airport where you’re going to take your flight, or the beginning of the airport name.

Language Translator. Now you don’t have to look dumb when in another country that doesn’t speak English. Beiks.com can be downloaded in your PDA to help you understand words and phrases in 26 different languages. Some of the programs would even help you pronounce the words right. You have to purchase the program though, starting from $8.

Weather Forecast. The quickest weather service would be the Weather Channel which provides extended forecasts for 98,000 locations worldwide. It looks as good as they would in a computer too.
