Yes, it's a Nook. I have one with TopHat too, but use a USB mouse GPS or my back-up generic Garmin with a serial/usb adapter. I take it home and download the igc file by USB. (ok for the OLC) It works very well so far.

I made custom clips for a RAM-HOL-TAB-SMU with a 1" ball system to the cockpit side rail. It covers the spare Winter mechanical vario I never use.

After flying four hours on the regular 7AH batteries with that and an audio vario, voltage dropped from 12.8 12.6 volts. One day I'll measure the current usage, but it's a non-issue.

I see no indication that it's too slow to do the job. On-line objections about speed or ghosting have been theoretical. Try one! It's cheap enough. :-)
