PDAs

For some time now I have wanted to invest in a PDA. However, for one reason or another, I never dedicated the money for the purchase.
PDA stands for personal digital assistant. I believe that I am like many people my age in that I am trying to transition over to using a PDA instead of a paper calendar/organizer. Many people are simply using PDAs and have completely done away with paper organizers.
It is hard to completely transition over to a complete digital organizer. I find that it is hard to have faith that the PDA will be reliable and not lose any of the data that I store in it.
