Query: Don't Gamble with Kindle

I received my Kindle in May 2008. I travel a lot and love that it fits in my briefcase. Last night I pulled it out of my briefcase only to see that the screen has a section that has become black lines. The text in this section of the screen in unreadable. I contacted Amazon and learned that the device is out of warranty and I have to replace it. They want me to buy another overpriced gadget? They need to wake up, while the reader is handy the goal is to sell books not gadgets. Their idea of good customer service is to quickly tell you NO. For the money I have spent for convenience I could have purchased many more books and in the future I'll do that from anyone but Amazon.
