I won't be needing the Palm to:
-Surf websites, -Send e-mail, -Phone people, -Play games
My Palm Requirements:
-Keep track of due dates, to do lists, -Looking up future dates and past dates for scheduling, -Take down notes , -A long battery life, -Keep track of contacts, -Easy on the eyes to read, -Keep a log of daily events
Seems the least cost model should do what you need (Zire 21) based on your criteria.
