Query: Kindle-a disaster!

I bought a Kindle in March 2008 and it worked reasonably well. However, the battery failed in September 2008 and I haven't been able to get a replacemet battery. Web blogs indicate that this is a widespread problem, but Amazon hasn't solved it. No other supplier has any batteries. So, I have an expensive device that doesn't work. I view this as a disaster. I marked this product one star only because I couldn't mark it zero stars. Do not buy this junk!
