I’ve been using a Palm PDA for over 7 years, and a computer calendar, address book, etc. for about 6 years before that. I could not function very well without having this information with me all the time! The last few years, I have used a Palm Treo PDA and cell phone in one, which is very convenient!
Here are links to articles on my blog about a few very useful Palm programs:
Datebk6 – This is where I keep my schedule and to do list (with repeats)
ListPro – this is one of my most useful programs!
