e Reader options for xc soar?

I've used XCsoar on a Nook Simple Touch for a couple of years and love it. I use it with a GPS USB puck and a Y-cable for external power. There have been a few glitches/freezeups, but if I start with a fully charged Nook there is rarely a problem. (Be sure to return its USB mode to "peripheral" and then fully power-off after you are done flying.)

I have yet to see ANY display, at any price, that is more sunlight-readable than the e-ink display of the B&W e-readers. The hardware is a bit flimsy but replacements are still easy to find and cheap. I added an extension to the snap-on-back that I use to mount the Nook with, to protect the USB plug from being bumped by my knee.

The Kobo seems like another option, but for me the simplicity of using the USB port of the Nook as-is is a plus, as is the larger display (and it fit in my cockpit, just barely).

We have developed a simple electronic device to connect KOBO with FLARM to get GPS, Baro and Flarm traffic. This "Soartronic OTX" module is connected to your glider's 12v battery, and it generated charging power to KOBO. Connection to KOBO is with normal USB cable, and with FLAR using straight RJ45 cable.. It also feeds 12V to your FLARM. And if you use external FLARM display, it has a build-in RJ45 splitter. Tested by Rob of TopHat in US.
