Per usual Sean F is obviously right about everything that he asserts and I would be a fool to try to debate any of the points that he makes.

I would only add that the disadvantage he cites of SeeYou and CE being stable and unchanged is simultaneously SeeYou's unique advantage.

Every time a program or operating system is changed, new defects are introduced, and all previous testing of the system, and the confidence engendered by that testing, should be discounted. People that use programs may not understand this, but the people that make programs certainly do.

The fact that SeeYou has been used for years, by many pilots, in many scenarios counts for something. It further suggests that SeeYou is usable and useful.

I agree with Sean that touchscreens are nice, but my arms are not long enough, nor steady enough to use them in a sailplane. I suppose I could hook up a trackball to an Ipad Mini?
