I'm your basic Luddite, but even I use a Blackberry for my calendar. I would't say I'm overbooked, but I have a number of activities and obligations that I need to keep track of. I was starting to lose track of things, so I decided I needed a better way to maintain a calendar

The nice thing about the Blackerry is that it's programmed to ding at me when I have an appt. Plus, it's synched to my work computer and email. It's helped me stay much better organized. I still don't have a home computer, but I love the Blackberry.
