Very interesting responses, and they certainly have me feeling that the iPad is the way to go. Probably the mini.
I have heard some say they would worry about hitting the wrong icon, or something along those lines, and maybe have it jump to a different or unwanted program, maybe just because it contains so much more stuff, that theres more things to get mixed up with somehow.
They'll say that a stand alone gps, in that sense, is more reliable to the user.
I have never heard it from someone who actually uses the ipad though.
From what I am learning, people seem pretty happy with the gps apps like Waze and Navigon. I have never seen or used them, I wonder if they are as user friendly as the garmin touch screens for the basic functions like, say, putting in co-ordinates on the fly, saving present position on the fly, maybe seeing your previous track lines etc..
Sure appreciate your thoughts and ideas, thanks !
