I keep that sort of thing in an Outlook Note and sync it to my BlackBerry.
True but the main reason for multiple copies is backup followed by access when machines are down. What happens if your Blackberry is stolen or broken or your machine is unavailable?

By keeping critical data in more than one place you are more certain that a copy will be around in case you really need it.
