thanks everyone for your answers, I know it will not improve my skills, but when doing time building, with a gps you will feel safer knowing where you are in case you get lost.
i will definitely go with the ipad mini, but i've seen some people saying that the internal GPS doesn't work properly for GA use. Is this true? my plan is to stick in close to the window with a suction cup, so it will be in direct view with the sky.
