The question is have you compared the free programs with SeeYou or
WinPilot. We would all like to hear your comparison.

I have compared GPS-LOG to SeeYou Mobile, and I am flying with GPS-LOG. It
gives me everything I need (X-country flying, no competitions) in a way I
like. It automatically switches between climb and cruise mode and displays
the relevant data for each mode without any need to touch the PDA. It gives
me the glide footprint on the map like discussed in another part of this
thread and AFAIK it was also the first PDA software to implement FLARM voice
warnings.

The only advantage I see in the commercial packages is the very easy
transfer of map and airspace from the desktop software (SeeYou -
SeeYouMobile, .....).
