Jon,
The white we are talking about is not like a floodlight but more of a soft
glow.
The contrast is much better than green.
Some of the reasons for the green backlighting are:
Longevity- Green phosphor lasts longer.
Sensitivity- The color green is at the center of the eyes peak sensitivity.
Cost- Green is marginally cheaper.
White backlighting is used in myriad notebooks, PDA's and displays.
If there was a problem you would not have such tremendous sales of these
devices.
But, if all this fails to convince you, I am also looking at a brightness
control, something that is missing from the original Newt ;)

I have a question. This talk about backlight colors, and the preference for
"white" got me thinking. My gut reaction to white is "ugh". Listen to my
reasoning. Wouldn't white be too brilliant for nighttime work? I mean, if
it's totally dark, and you turn on the white backlight, the starkness of it
would hurt, wouldn't it? Does anybody have any experience with white
backlighting? Isn't that why the lighting is green? so it isn't too
brilliant? Very curious to hear the pros and cons and whatnot...
