I have been patient and waited for a few years. I finally ordered a 64GB iPad 3 and got a note from Apple that is on the way from Chongdu, China.
Recently, Practical Sailors and one of Sailing Magazines did an article about the CharPlotter programs. I read both carefully and like what I read. I have made my decision, but I like to hear from others who have actually experience using it. More importantly, what you don't like about the program or its deficiency.
