- You're just lucky, basically. Screen burn-in comes from leaving a monitor
- (or TV) displaying the same image for a long period of time. This problem
- happens a lot in electronics stores where they have a video camera hooked up
- to a TV so customers see themselves. Often the people will look like ghosts
- because the background has been burnt in. Same thing happens a lot in any
- business where they use a computer all day -- typically the same screen is
- always displayed and eventually it will burn into the screen. The bright
- colors get burnt in, so a black-on-white display could do more damage, but
- either way it is going to be noticeable.

- Is it? My guess would be that black-on-white is used on the Mac only because
- it resembles a piece of paper. Any DTP application will typically have a
- black-on-white display.
