I am flying with a Nook Simple Touch, loaded with TopHat (a derivative of
XCSoar, see: tophat.freeforums.org), connected to a Cambridge 302. The
display is superb in direct sunlight and the update rate is immaterial,
given that I use the instrument for occasional quick reference, not
detailed and continuous study.



I flew with the Nook running Top Hat for the first time this weekend. It
updates at least as fast as my old PDA. Ghosting was not an issue at all
although I did not enable terrain. I did have roads and rivers turned
on. The Nook is connected to a GPS puck and ship power by an
off-the-shelf OTG ""y" cable. It was stable and held GPS lock for a 2.5
hour flight. Previously, I had tested the setup in the car for almost 3
hours and it worked perfectly there as well.

What a joy to fly with a big display that is actually visible in
sunlight!

Top Hat is thankfully pared down a bit from XCSoar. XCSoar and LK8000
both have too many features IMHO. So far Top Hat does everything that I
want it to do and is simple to use.

One feature that I did not try out: The thermalling assistant. I already
have a great thermalling assistant. It's called a 301 Libelle. She
shakes and wags to tell me where the lift is and I can even keep my eyes
out of the cockpit.
