Hori is a company that makes screen protectors! The whole story though... I discovered the Hori brand screen protector (or Hori) after getting a PSP. Those things have a nice screen, and as previoulsy said- I'm a nut-job when it comes to my portable devices! I only ever used a special sunglasses chamois (not even the cheap one they include w/ the PSP) and the screen looked real nice. One day I got it in the sun though, and with the unit off I could notice (what the PSP forums termed) 'microscratches'. Sure, pretty unnoticiable, but still...

So I did some reseach and found the Hori brand to be well established as 'the best'. I bought a regular screen protetor and put it on my glass monitor to test, and it made the screen seem all junky, and you could easily see it was a protector. Then I eBayed one and WOW! The Horis are 100% clear, you cant tell its on there. Also, it adds a glare filter, and is removable for cleaning.

If you are lucky enough to live by a Fry's, you can get them for about $6 each. I recommend you get 2 for any project, because they are very tricky until you are used to them. They are made up of multiple layers, including a silicone-y bottom one. Also, you can wipe them with your shirt or pants... whatever, they basically dont scratch at all! (They make them for DS too!)
