I used to carry around one of those Franklin Day Planners that my employer paid way too much for. It had ALL of my phone numbers, addresses, appointments, special dates and info, etc., etc. in it. I left it in my truck one night, the very night someone stole that truck right out of my driveway. That was like 3 years ago, and I'm still trying to track down numbers and addresses that were in that damn thing. If it had been a PDA, I could have just bought a new one and sync'ed my data back into it from my PC.
