"Personal" Digital Assistant

Since monday my Zire 72 has been lost. At first I thought I just misplaced it and figured it would be in one of my routine spots. As the days passed and the list of routine spots diminished I began to worry. I kept so much information on it that the feeling of somebody else grabbing a hold of it was starting to disturb me.

Come to find out it ended up being in my clothes hamper. Not sure how that happened but I am happy to have found it.

Now I'm thinking about the data on it and how personal it is to me. I already do daily backups (syncs with my PC) but the idea of somebody finding my data is not a comfortable one. I could setup a password but not sure if I want to go back and forth with it everytime I use it.

Of course the simple solution would be "DON'T STORE PERSONAL DATA ON THE PDA"...

Any thoughts?
