The Universal Packing List

From Lifehacker:

The Universal Packing List (link) is a terrific online application that allows you to build a customized packing list, complete with reminders and tips, for any traveling you’ll be doing.

It works by having you fill out an online form with details about your trip, and some details about the kind of list you’re looking for. Then, based on your answers, it gives you a customized list of what to pack as well as some general advice and reminders. It’s very simple, yet very effective.
