The gizmos on the market have enough functionality built in them that outside software is often not needed.

A bunch of years ago I was a training manager for a 500 person squadron in the Air Force. Of course I was expected to know who was in what training class at any given moment or who was going to be any time in the next two weeks. I had a PalmPilot Pro that I bought a $5 shareware program for that allowed me to see dates in snapshots. Best $5 I ever spent.

I reiterate.. +1 on benjammin's input
