Bill,
Don't get just a plain PDA - I have had both a PDA and many "smartphones". I am a Palm OS person and like all of the products with the Palm OS. I caved in 3 months ago a bought a "Windows" OS smartphone and can say without doubt it is a Piece Of S**t. I spent a lot of money on it and will trash it and go back to my Treo. I have had several through the years and really have liked the Treos. I have no experience with any Blackberry phones but everyone I know who owns one seems to like them.
