sunlight readable iphone

I am something of a collector of these things. I have an LX9000 in the panel, and fly with an Oudie IGC running standalone as an additional display. The PF feeds traffic to the LX and to a Butterfly.

When in another glider I use the Oudie IGC - fully standalone, an IGC logger, what I consider to be a great interface (if you invest the time to know it and to set it up), and with a big internal battery. I think it is the gold standard in standalone devices, and has significant advantages over the expensive dedicated devices such as LX, Zeus, Clearnav and Air Avionics.

I also own an S8 on which I have XC Soar and Skydemon - also Tophat but I prefer XC Soar. I changed from iOs to get Oudie Live and XC Soar. I carry it in the pocket of the glider but have never had to turn it on. When flying power I use Skydemon on the S8.

I also own a Kobo Glo HD with Bluefly vario/GPS bought from http://gethighstayhigh.co.uk/
running XC Soar. I don't use it. IMO the benefits of colour and a phone touchscreen make the S8 a better device for XC Soar than the bigger and superb in sunlight eink device.

All these devices are fine for sunlight readability IMO, unlike earlier generations. Early monochrome iPaqs were good (I used Winpilot) but from the time colour came in until the Oudie 2 sunlight readability was a real issue. On these devices it isn't.
