1. Duplication of information is bad.

  2. See point 1.

  3. Computers are good at keeping track of detail, I'm not.

  4. The Palm isn't very good at storing relationships between records. (This conference is in my date book, this hotel is in my address book. I know they're related, why doesn't my Palm?)

  5. I also want to keep track of relationships that are outside of my Palm. (I'm flying to Montreal, what's the weather like?)
