I love Outlook and I have Chapura's link so when I synchronize with my Palm it has the same data. You would not use the Palm address book if you did that.

A trick I learned about using Outlook for your address book is to put a character in your email address like an astrisk at the end of the name (ie karen@brownandkeene.com*) so that emails would bounce back to you if you did get one of those worms who hijack your address book. The worm won't spread. If you send a lot of email you have to delete the astrisk every time, but, it's preventative because you know right away.
