You know, I thought about this the other day...
The cool thing is that it doesn't require alot of power and it can be
connected to a pocket pc with special software...

However I use this:
http://www.pocketgear.com/software_detail.asp?id=19129, and what I do
is everyday before I go to fly I turn on the computer and sync the
programm and drjack files (all automatically) works good, I have 2 hot
buttons assigned, one to show dr jack, the other to show this programm,
so I can view them during flight with the click of a button...
