A greyscale version of XCSoar and TopHat both flicker free and very daylight readable.... fantastic. The more sun you have the easier it is to see !

See, that's why using open source software is good - TopHat has figured out the "flicker free" thing on the Nook, and XCSoar 6.7 copies that part of the code. Copying is not bad - it helps everbody, because each benefit in one project will be available for all projects, and in the end: for all users of all projects.

I'd like to mention that XCSoar 6.7 runs very well on the Kobo Mini. That's another e-book reader that costs just 38 EUR! (in Germany)

The Kobo is faster than the Nook, and comes without Android crapware. You can boot right into XCSoar, and booting (from power off) takes just two seconds.
