Sorry to swerve from the topic just a tad but you have me wondering.  I find
that after more than a minute or two, my Newton's screen goes dark if the
sunlight truly is direct.  My solution is that I make a point of turning the
screen so the sun isn't directly on it, or else is in the shade.  The
alternative is for the LCD   But since my polarized sunglasses 'light up'
the Newton screen, it's no loss of visibility.  In fact, indirect sunlight +
polarized shades are an improvement if anything.

So my question is, why doesn't your Newton go dark in the direct sunlight?

 
Shalom.
