With 7 buttons, two knobs, and a 114 page manual I'm not sure Zeus has broken any new man-machine interface barriers. Imagine if Google maps on your cell phone came with a 114 page manual.

Fitchy, Keep in mind those buttons are labeled , unlike some other glide computers. I should have said GUI instead of UI. The LXNavigation stuff at the show had some of the best looking (And yes easiest to interpret) screens of anyone. And thats coming from an LXNav guy. Also, why do you assume instrument manufacturers would use dated technology in regards to touch screens. The stuff displayed at the show was cutting edge in both accuracy and brightness.
If Google Maps could do what my glide computer could I would expect a 114 page manual.FWIW my S100 manual is 105 pages and still leaves a bit uncovered. When you consider the capability and versatility of these things 114 pages is nothing. Even for people like me with short attention spans.
