When you're on a plane (or in another public place), do you take a peek at what's on your neighbor's laptop screen? Tuesday's USA Today story on laptop etiquette quotes a survey that says 45% of respondents admitted to glancing at someone else's laptop screen while in public places. Worth noting, however: the survey was sponsored by 3M, which makes screen filters that prevent others from seeing what's on your screen.
At any rate, the point is we like to peek. Meanwhile, a growing number of laptop screens use high-contrast, high-gloss technology, which makes the screen easier to view from either side. Add the fact many of us watch DVDs with at least some adult content--a brief nude scene, for example--on planes or trains. What've you got? The growing likelihood that you'll look up from your organic fruit snack, only to see two people on a nearby laptop screen doing what comes naturally.
Bottom line: Be prepared to lower your laptop screen when you're viewing adult or personal content in public, to prevent others (such as nearby kids) from seeing it. Or invest in a 3M laptop screen filter. I've used them; they work as advertised. The clip below is an amusing ad for the filters.
