Power it up
Perhaps the biggest limitation of a PDA is its short battery life. There's no point bringing your handheld along with you on your trip only to have it run out of juice when you need to check your carefully-planned itinerary.
The problem is less acute if you use a Palm III series PDA, because these run on batteries. Bring your own extra batteries, or buy them wherever they are available along your trip. But if you're using the Palm V, things can get a little complicated since it uses a rechargeable lithium ion battery. Instead of lugging your PDA cradle halfway round the world, you might want to bring the Syncharger instead. This nifty device is a portable charger that runs on batteries and allows you to charge up your Palm so that you never have to worry about your Palm running out of juice.
For those using the Pocket PC, it is wise to bring your AC adapter and charge your handheld when you're running low on power.
