Your post helped... I dropped my new Kindle DX on a marble floor today and after the initial desire to vomit after it bounced a few times and landed face down passed, I picked it up to assess the damage. The device is fine functionally, but I lost a tiny chunk out of the bezel and a portion of the bezel on the edge popped out of alignment.
The only way to fix it (not counting the missing bit that flew into corners unknown) was to pop off the bezel and reattach it.
For someone who has the same problem: I put the Kindle face down on a counter, then put one thumb at the bottom of the gray bezel directly under the sleep switch and my other thumb at the same distance in from the left side. Then I pushed in with my thumbs and up. It slid off easily and I was able to slide it back into place where it was before the Big Drop.
Thanks for your description!
