Everyone I fly with dislikes it. I have used it in conjunction with the original electronic flight plan for two flights then used it by itself on three flights. I found it unnecessarily clunky. I am sure getting use to it will help a lot but that will never fix its inherent clumsiness and slower access to many things. I flew with someone who used it early on and reported back to the working group what he thought would be important fixes. He was told he just had to get used to it and thanks for your input but we aren’t making any changes.
