Zagg makes the InvisibleSHIELD line of gadget protectors.  The one I install in the video above is for my Canon DigitalRebel XT camera, but they make screen protectors for a dizzying number of cameras, phones, laptops, and more.

Bottom Line

Installation is quick and easy, and it really is invisible once installed. For a couple bucks, these are a pretty nice investment for protecting the display screens on your expensive gear.
