BadAstronaut,
"Inversion" is what happens to the pixels on the Visor when the backlight is activated. I'll assume that you know already that the screen is a grayscale LCD panel. Well, when the backlight is activated, all of the pixels that were activated deactivate and those that were deactivated activate. (Sorry for my confusing language) In other words, the white areas become black and the black areas become white. So the screen will in one respect look like an old DOS screen, where all of the characters are illuminated, while the rest of the screen area is blackened.
I think Palm chose this route, and moved away from the traditional, non-inverted light, because it's easier to read text. It's just a little annoying though, because you can't use positive-dependent features, like image viewers, without seeing the funky negative image. I've grown to prefer inversion, because it's much less distracting (or attracting) in movie theatres, where the traditional, bright backlight would turn heads.
