For a few years, I’ve always traveled with my Palm III or my HandSpring Visor Prism, which replaced it. Except for an occasional game, I used it mainly for my contacts & schedule. The iPod can do both, although I can’t edit or add items.
The iPod can even display alarms for appointments, just like the Visor does. It also makes a nice external FireWire drive. This is a perfect example of how Apple designs a product that goes above & beyond others in its category. It’s a lot nicer than any other MP3 player I’ve seen or used.
