Sorry, but iGlide/iPhone IS a complete full blown gliding computer with a comparable feature set to the Air Display L, LX9000, or Oudie IGC. You are clearly unfamiliar with these systems.

I own Air Glide system, and fly Oudie (incl. IGC) and LX9000 on regular basis. Plus various other gliding computers, of course.
