Which PC Flightplanning Software EFB Would You Recommend?

Hello!

I will be getting a tablet PC (thinking about the Motion Computing
LE800), and will be buying a flightplanning software package for IFR
soon. I've been looking around at all the different options (Seattle
Avionics Voyager/GlassView), RMS FlightsoftPro/Vista, FlightPrep,
EverywhereMap, etc. It is quite confusing. It seems that Seattle
Avionics is the most reasonably priced, but SLOW! FlightPrep looks
nice, but at $500/yr, a bit too pricey for my blood. Flightsoft seems
like it might have everything, but not sure, and they don't allow a
trial download. What are your experiences?

Thanks!
