Glider computers - what's important?

I initially used GPS-Log. GPS-Log does have a PC simulator. It gave me
some insight into the value of a flight computer.

I subsequently switched to SeeYou Mobile for ease in loading my PDA with
maps, airspace, waypoints, etc. I may not have fully understood GPS-Log,
but I was doing a lot of handcrafting of files. Also, I think SeeYou Mobile
screens are more customizable. I keep changing mine as I haven't yet
settled on what I like best.

On the support side, Henryk Birecki (software developer) was always very
responsive to emails I sent. He is active in the Yahoo Group for GPS_Log.

Finally, my choice of SeeYou Mobile over Pocket Strepla or WinPilot was
based on the fact that I had previously purchased and learned to use SeeYou.
I'm very happy with SeeYou and I believe my life would be less complicated
if I used the PDA version of the product in the air.
