I've been experimenting with a old 6 inch ebook reader, the Barnes & Noble NOOK Simple Touch. It's been rooted so it's possible to sideload APKs onto it. Anyhow XCSoar installs seems to run ok on it, it connects to the PilotAware and displays traffic and airspace. Don't think it'll replace skyDemon for me but it might be of interest to folk looking for a daylight readable screen as an alternative to the Kobo Mini, mine was very cheap when they were being sold off as end of line. Hopefully I'll get chance to take it flying this week and see how it performs in the air.
