My 3 year old Mac has, like all Macs, a white menubar in exactly the same
place with exactly the same items in the three left-hand positions
practically every minute it's on with the screen-saver inactive.

I've never seen any evidence of burn-in on any Mac screen - even the 9 year
old Mac Plus I've just bought with its little b+w screen seems to have

The only times I've ever seen burn-in are this: once on a 1970s vintage
colour television connected to a home computer that was in heavy use for a
year; and on several cheap b+w monitors connected to Amstrad PCW512s used a
WPs in an office - I think they'd been on 8-12 hours a day, running a DOS
text menu driven system for at least 3, maybe 5 years.  It was possible to
read the main menu when the monitor was off!

I'd guess that the average colour monitor these days doesn't have to worry
about burn-in.
