Thanks for the link. I was looking at the Infinity 7 video on the Sierra website two months ago and my impression was that they were using a phone app interface. Great on a smart phone, but on Windows I want a windows interface where I can open the parts of the program I need and go between them in any order rather than paging back and forth to get what I want.
I'll go through the user guide and see if I was mistaken and if 7 is improved enough over Infinity 6 to justify the price.
