I'm not so sure I agree - I would have thought I would have agreed, then I flew it. It really is nice to "point and go." We have a GTN750 in our Pilatus which is touch-screen, it is actually the easiest GPS installation I've ever used. Not only that, but it took about 5 minutes to learn. I like it better than anything else I've ever worked with for a lot of reasons. We have a G1000 in our Caravan which I like very much, and I wish that was touch screen. I find a touch screen GPS way more "user friendly" to navigate through than the 430/530 system by far (and I have several thousand hours behind those).
Why is that? I find it easier to use than our 430/530 combo when I fly our Navajo, and honestly, I find it easier than the G1000 install in our Caravan?
