get a "no-key" skin-search on amazon for 'no-key'. They come in a lot of different designs. These skins do not have the holes for the keys, but have the letters on the vinyl that covers the keys....makes the keys very easy to read.
I recommend Lori C suggestion. I bought a "no-key" skin a month ago and couldn't be happier. The only problem I had was deciding which design to choose! One thing to note is that the skins come in glossy and matte finish. Just wanted you to be aware of that in case you have any concern about glare from the skin. Many designs come in both styles, you just have to keep searching for it. Hope this helps.
Also, in other forums, I've read that Kindle will replace yours if you request it. But I also read that some have been replaced with a refurbished, not new, Kindle. If you choose this route, ask to be sure of what you'll receive.
