Query: Good economy pocket viewer.....

I actually bought this unit used on Amazon.com and has worked perfectly for me. When I am using it people come up and ask if it is a palm pilot. If you are just looking for an address/reminder/note pocket viewer, this is great. I really like it and it does exactly what I need. It hasn't lost any data and seems to be high quality. The only setback is sometimes you don't want it beeping everytime you press a letter or function. That gets irritating when you are in a public place and want to add information to your organizer. Otherwise I am really happy with it. I don't need all of the other functions of one of those expensive palm pilots, I just wanted a note keeper/address organizer.
