If you often bring your netbook in a cafe or in any public area with Wi-Fi hotspots, you may not be aware that people nearby may actually be staring at your screen. I've experienced this often especially when I work inside a Starbucks Store.
To prevent other people see what you're working on, you might want to consider getting the 3M Gold Privacy Filter. This 10.1-inch film is perfect for all 10-inch netbooks and offers ample protection that prevents other people especially those looking from your side angle, from seeing what's on your screen.
Aside from this, the 3M Privacy Filter film also gives your netbook screen additional clarity. It's actually a two-product in one – a privacy filter and screen clarity enhancer.
This privacy filter film is available in the U.S. via Amazon for $30+
