Though laptop users have long been able to buy privacy filters for their computer screens, cell phone owners haven't always had the same luxury. So if you're a passionate texter worried about protecting your precious messages from prying eyes, there are now cell phone privacy filters just for you. Available in a single 3.14 by 2.36 inch sheet, the privacy filter should fit almost any cell phone on the market (you'll just have to trim it to fit your particular model). Though we agree it's an interesting idea, we also see it as just another piece of consumerist junk you don't need. But at $13 it won't break the bank.
