Hate people standing over your shoulder and anxious about people seeing what's on your computer screen? 3M has recently launched a privacy filter that can mitigate (and hopefully eliminate) this problem.
3M's privacy filter is actually a piece of plastic that is placed over the netbook screen to restrict the viewing angle. For those sitting directly in front of the computer, reading and seeing what's on the screen should not be a problem, but for those looking at the netbook at an angle, they wouldn't be able to see anything on the screen.
If your netbook has either a 10.1″ or 10.2″ screen and you're interested in getting a privacy filter, click here to get one from Amazon for as low as $33.24.
