Chances are, you're probably the type who does better with an actual date/address book.
My father has tried the PDA thing for years and he always falls back on his date book. He just has a secretary update it every couple of days by hand.
One use for the PDA/phone that you might find useful is to set up a new email address for use with the smart phone. Once that is done, you can set up an email filter on your work computer (if you leave it on), and messages that meet certain criteria will be forwarded to your smart phone's email. That should cut down on the emails you get on your smart phone.
The question is do you actually keep your computer date books and address books up to date? If not, don't expect to start just because you bought a smart phone.
Thanks for the input.
No, I keep my calendar on my computer and my task list there up-to-date religiously. I do HORRIBLE with "regular" hand-written calendars, etc. I really like doing the calendar electronically. Let's say you sent me an email inviting me to lunch at a specific place tomorrow and you included directions along with names of people who would attend. I would just drag the email to my calendar, your written directions and all, and the directions and everyone's names (because I'm horrible with names) would be there in my calendar both for use in the present and to refer back to. Of course, in the "old" days, I used to print the email and paperclip it to the page the date is on, but then my binder got to heavy to carry.
