Jim,

I like Top Hat and am intrigued with the OpenVario, as you will recall from my interest in your installation last fall at R4N. There is a Linux download of Top Hat on their site as I write this and I've seen reports of at least two OpenVario users who have installed Top Hat, one Android and the other Linux. No info on how well it functions.

One important factor is that Top Hat (derived from XCSoar but focused on competition) has some nice features for a touchscreen interface, the most critical one being the navigation bar at the top of the main screen. Slide it right or left to advance/return to a next/previous TP. Touch to bring up a task menu with various options. It seems to work fine on my PC in a click-and-drag mode. Can that be done with OpenVario with your input devices (SteFly stick and/or rotary controller)? I suspect, though don't know, that most of the info boxes, menus, and inputs would work similar to XCSoar.
