Losing your PDA is bad enough, given the expense and inconvenience of replacing the hardware, but lost data can pose an even greater problem. When you lose your handheld, you lose all of the data you’ve entered since your least synchronization. Even worse, all the sensitive data on your handheld is exposed. Whoever finds your handheld can read the data, copy it, even publicize it unless you take steps to protect it from prying eyes.
 
Do you keep personal email, private files on your handheld? Would you want others to have access to that information? The good news is that with a small amount of effort, there are steps you can take to protect your sensitive data.
