Ditto (including the "I could be wrong.").
Two recent experiences (I've read outdoors in the shade before and never experienced fade):
- Sony PRS-505 reading in direct sunlight (I was testing for the fade) for about 10 minutes. Ambient temp about 75 deg. F. No fade.
- Same Reader, first sat for twenty minutes in direct sun in a black case. Ambient temp about 95 deg. F. Metal parts of Reader were hot to the touch from sitting in the case. Definite fade.
Edit:
Further testing of my dark blue PRS-505. Ambient temperature today: 100 in the shade.
- Read in the shade for about 2 hours, unit didn't feel hot. No fade.
- Placed 505 in the sun for 10 minutes, unit felt hot. Infrared thermometer read over 135 deg. F on the dark blue back, and over 130 on the screen. Fade showed as soon as I turned the page.
- Fade disappeared by the time the screen temp had fallen to 115.
So IMHO, I don't think I have a "fader." The fading occurs when the unit feels to be far too hot to the touch for an electronic device to be expected to perform correctly.
