This is a great idea, very useful to protect your keyboard. I think that computer companies should always integrate this kind of protection to the keyboard. Keyboard aren't cheap, and on laptops if you spill your coffee, your laptop is pretty much dead. So this comes in as an important piece of protection.Unfortunately in low light environment, especially when there's still enough light for the backlight of the keyboard to be off, you just can't see the keys anymore. Because of this issue, 1/2 of the time i'm not using the protection. The protection is very sticky on the side that goes against the keyboard, meaning that when you don't use it, it gathers a lot of dust very quickly, beating the purpose of having that "skin" on top of your keyboard.Another good idea, that really needs more thinking, as to what material should be used so that it's fully transparent.
